[quote name='BigRedX' timestamp='1487243103' post='3238278'] The fuse in a detachable mains lead is there to protect the lead, not the equipment it is attached to which will have its own appropriately rated fuse. The difference between a lead for a kettle and a "kettle lead" has already been adequately explained in previous posts. Surge protectors/power conditioners and similar are only really required in places like the USA who have a considerably less than robust electricity supply compared with the UK. IME when there have been mains problems in this country nothing less than a properly spec'd UPS would have been suitable. [/quote]Correct this is why "power conditioners" are big in the USA and not here. Much old waiting in the US was done with aluminium not copper and that is more problematic, much noisier. Surge Protectors and power conditioners are sna[size=4]ke oil over here. [/size]

if you are using "dead " flats many treble controls will not add much.

[quote name='T-Bay' timestamp='1487691691' post='3241878'] Having designed and built electric race cars the dealings I have had with electronics engineers over the years have had me pulling my hair out. I have only met one reliable one in all the years and he is now one of my best mates. He is the first to say what an unreliable bunch they are as a whole. Good ones are in such demand they can get away with being unreliable and troublesome in ways other trades can't. Bad ones still get by as often they are the only ones you can get to look at stuff as the good ones are so busy! [/quote]Are you talking about Engineers, Technicians or just repairers?

Jack every cabinet from Behringer to Bergantino and Barefaced are compromises. There is no such thing as a mathematically perfect cabinet but some are better than others and some suit some people more than others.

When they 1x12 Design Diary was started by Phil Starr and Stevie, the aim was to produce a 12" cabinet that would keep up with a loud drummer (i.e. 120dB). The cabinet that was designed di that and at about 250 watts if memory serves correctly. two cabinets should really be able to beat that is they are efficient.

The problem is with Class D, too many people hyped what it could dom and with names like Cool Amp and ICEPower. The legend lives on. ICE by the way is for Cool not In Car Entertainment as some continue to call it. Although Class D runs MUCH cooler than class A/B, It does generate some heat . As a rule of thumb about 17% of the rated output is heat so for example a 100W amp will produce 17 watts of heat based on a true output figure and an average efficiency in both power amp and power supply of 90%. A 500 watt amp will produce almost 100W of heat, the same as an incandescent 100W light bulb. Put that amount of heat into a small container and you could have trouble. Now here is the rub, the amount of heat generated is only partly the result of increased power output. There is a quiescent heat generated even at zero watts out. That quiescent heat depends on the design but is usually about 10-15% of output power so 50-75 watts at no output. So to keep heat under control, you need heatsinking and/or a fan or two. Nowhere near as much as a class A/B amp but it is needed. In a 1U chassis there is restricted airflow so heatsinking does not work so well and 40mm fans do not shift a lot of air. Also fans are a lot less reliable than heatsinks, although a lot lighter. Then you have to fit the preamp and connectors in. [size=4]Going to 2U makes life simple and solves most of the problems and that is [/size]what[size=4] a lot of amps are [/size]about[size=4] 2U (88mm or about 3.5") high even if they are not 420mm(19") wide.[/size]

Just one question, Jacks or Speakon? If your amp has jack outputs that could be the culprit. I remember one amp manufacturer putting a very high percentage of power amp failures down to shorted jack cables.

Go for it. Many commercial cabs break many of the rules and are revered. I am sure your cab will be more than useable and what have you lost. You can also come on here and say I told you so Your expectations are low and you might have a very pleasant surprise. So build it and tell us what YOU think.

Yes the voltages were unified way back in the 80s I think. Thank you EU [size=4] [/size]

[quote name='scrumpymike' timestamp='1487246261' post='3238318'] "Early start of me as although everyone thinks of Poole as being SW it is really south so don't spare the coffee." Coffee? You'll need a blood transfusion after that drive! [/quote]The problem is that Poole is miles from anywhere except Bournemouth and Southampton. Neither of which are worth the petrol money. In the absence of blood, will there be the next best thing? Real Ale! On a serious note I can now confirm that the new design Basschat 1x12 plus Compression Horn cabinet will be at the bash. The design is complete so I just have to build the cabinet and the crossover and cover it and make a grille....should be done by the 1st April.

[quote name='stevie' timestamp='1487244539' post='3238291'] Just make sure you use a proven design or get some advice before you cut the wood. This thread - and I think the OP will agree - is a good example of how not to DIY. [/quote]I know Stevie and Phil Starr are both a little coy, but if you saw how much work has gone into the Original 1x12 and the new 1x12 threads on here it is clear that the best performance is designed in not stumbled upon by chance. If you read Stevie's write up you will learn enough to at least make a considered opinion about your next build/purchase.

[quote name='Beer of the Bass' timestamp='1487241256' post='3238256'] Aargh, car analogies! But if you could make the Rover work significantly better with about 20 minutes work using tools and parts you already had at hand, you'd do it, right? [/quote]Of course when Rover put that V8 into the 3500 you had a serious motor. Maybe not a Ferrari but the it did not bend servicing every 500 mile like Ferrari did in those days [size=4] [/size]

I will bring my Fender Aerodyne, Greg Bennett (Samick) Semi-Acoustic (that reminds me I must do a NBD for that), My home brew 500W amp and maybe a surprise? I am looking forward to trying My Chowney's basses and comparing them to the Greg Bennett. Early start of me as although everyone thinks of Poole as being SW it is really south so don't spare the coffee.

I am up for it.

king at the Dood's review, he said that if you zero the EQ controls you get no output. This suggests a passive Fender type tone stack like the original Bassman (and guitar amps). The output valves are KT88s. These are real beasts and knock 6500s and EL34s into a cocked hat. So I guess this is a real old school amp (pre amp). ~Maybe it's the Bassman Fender should have built?

Phil is right and the jump from 450-500 watts is unlikely to has caused the problem. Just take it as a random failure and as it has been fixed it is unlikely to blow in the same way again.

[quote name='markstuk' timestamp='1486757244' post='3234426'] True, but it's all relative anyway.. It's 3db extra.. Markbass published the number so I assume if it's crap it's relatively the same crap for all of their cabs [/quote]Lets hope so but many manufacturers will use a voltage to measure the on-axis measurement, rather than the standard 1W. If you use the same voltage for 4 & 8 ohms ..voila the 4 ohm cabe is 3dB louder (not).

[quote name='Gottastopbuyinggear' timestamp='1486732440' post='3234184'] Full disclosure - I have one in the for sale section at the moment. I'm honestly not trying to push it! If you just want it for monitoring purposes and you're going through the PA for FOH then I'd suggest you'd have no problems with it. I have one which I've used in rehearsals with fairly loud drums and guitars, and I had no problems getting heard with just a GK MB200 driving it and the gain on about 12 to 1 o'clock. The only time I struggled with that combination was the last time I used it with my last band, in a very small rehearsal room with two guitarists both running 100w 2x12 combos - and they were running them (too) hard. I use earplugs, and even then the volume was far too much for me - I actually quit that night on that basis. Are you using Markbass cabs now? I'd say the 102P has a similar "signature" sound - quite mid prominent - though you'll get less lows. The bass is pretty tight to my ears, so quite a defined sound. I've not experienced the issues some people have with the tweeter being hissy. I sometimes had a bit of difficulty getting a sound I was completely happy with when using a P bass, which I put down to the P being mid prominent, and me being a bit inexperienced. I did get a great (to me) sound with a Jazz. [/quote]Tweeters are not hissy, amps are. Hiss is the sound of an amp that uses cheap Opamps and carbon resistors.

[quote name='Beer of the Bass' timestamp='1486761829' post='3234477'] Transformers aren't cheap, essentially. Companies like Bugera keep costs down as far as possible through economy of scale and keeping everything in-house in their Chinese plant, and that's about as cheap as they can be made. Even then they've had to discontinue models that presumably weren't paying their way, like the SVT knock-off. I build valve amps as a hobby, and I don't think I could buy new decent quality parts for a 50 watt head for any less than about £300, and that's with a lot of shopping around. Ok, that's at retail price, but it gives you some idea. [/quote]Go for 100W and you can up that by a sizeable amount twice as many output valves and double the VA on the two transformers. The transformers are done in small runs , unlike the ones in say a solid state A/B head where the transformers are off the shelf. There is no reason on earth that I can see why anyone would start a new business selling Valve heads. There is a joke that goes like this. How do ups make a small fortune owning a football club? Start off with a large fortune. I suspect you could replace football club with Valve amp maker. Of course there are some enticed by the mystique of the odd boutique make and will pay more than I think they should but it is not a volume business for a new entrant to the market.

[quote name='markstuk' timestamp='1486674233' post='3233802'] And don't forget that 4 ohms also gives you another 3db over an equivalent 8 ohm cab.. [/quote]You have to be careful here. Few (if any) bass reflex designs cab reach 103dB 1W/1M.

[quote name='bassjim' timestamp='1486739014' post='3234271'] Going by the blurb on the BF site I though I was going to really like one. When I tried it I didn't. Not even a little bit. Stayed where I was but at least I knew that I didn't like it through personal experience. I got to A B it with my usual brand. Alex let me pick one up and try it which was very nice of him. So now I know. You may find unless your ears are used to something different you may like them straight away. However they do seem to be a winner for many so if the try before you buy thing is still going....... [/quote]This is the point. It is the best for whom? If you love the sound it is the best, if you don't, it ain't. I suspect there are BF 1x10 owners that would also argue with this.
