Mr. Foxen

I didn't like the sealed Hydrive 4x10 at all.

[quote name='paulwillson' timestamp='1333995412' post='1609394'] I wonder what the differences are between the 400 and 400+??? they look the same [/quote] Totally different power section using different valves.

Lots of arm waving accompanies drone, so everyone can see when to him the next note, because they only come every few minutes.

I took it off my old bass that really wasn't worth the upgrades I put on it. Those are still available on ebay. I like the topload system an smoothness.

Possibly a bad connection somewhere, pull off an put back on spade connectors, resolder everything.

Assume this is a faker from the weird listing an start price, worth an email see what he's really after: [url="http://www.ebay.co.uk/itm/Bass-Guitar-/280860667662?pt=UK_Musical_Instruments_Guitars_CV&hash=item416499af0e"]http://www.ebay.co.u...=item416499af0e[/url]

[quote name='paulwillson' timestamp='1333851390' post='1607425'] Mr Foxen, what should i look out for when replacing the power valves then? Just trust mike hill? how much did you pay for yours new Chris? [/quote] An amp designed for having its power valves replaced. The issue is with the amp, not the valves. Edit: There is a well known mod to add adjustable bias, but not sure it it is an overall or a pair of adjusters. Pair is better as you can adjust the balance between the push/pull halves.

I did just remember that the applicator of my Dunlop oil shed fibers for ages, was a bit annoying.

[quote name='paulwillson' timestamp='1333844709' post='1607387'] Mr. Foxen thats really interesting i assumed "hand matched" really meant the tech was looking out for me, please tell me i havent been lured into marketing buzz word buying [/quote] "hand matched" is even worse, hands don't tell you anything about electrical properties, maybe he picks them out of a pile and matches up the logos. Stuff has to be matched to the fairly specific conditions in your amp. And without a stated tolerance it is definitely a marketing buzzword, they could be matched with an enormous error margin.

Lemon oil can mean various things, some that is basically detergent is what gives the 'makes it worse' idea. Other stuff is actually oil. I'm using the dunlop 65 stuff currently, seems fine.

[quote name='chris_b' timestamp='1333841068' post='1607345'] Unspecific 410? What are you talking about? [/quote] As in 'a 4x10' rather than 'an SWR Goliath III'. An SWR Goliath III is specific, with a specific associated sound, the is no sound specific to 4x10s except for poor off axis response.

[quote name='chris_b' timestamp='1333838658' post='1607317'] I would recommend Barefaced to anyone, but if someone wanted a 410 they should not be confused at all, there are some very good ones around these days. [/quote] The fact someone wants an unspecific 4x10 demonstrates that they are confused, because they are under the misapprehension that being a 4x10 has some property other than 4 10" speakers. Every beneficial property of a cabinet containing 4 10" speakers in the familiar square formation can be done better with no downside by other configurations. You can't even 'let your ears decide' because ears aren't in the right place to do so.

I got a roll of this, its working fine for me, I get through solder, this stuff is quite fine: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=360434145079&ssPageName=ADME:L:OC:GB:1123

Don't really keep toy amps in stock.

[quote name='REDLAWMAN' timestamp='1333805502' post='1606751'] Thanks very much Balcro & Stevie; very much appreciated. I'll drop Eminence a line as you suggest. Mr Foxen: if I didn't know better, I'd think you have a crush on me. You seem to have made commenting on all of my posts your raison d'etre...... [/quote] You appear to have a lot of money, an a desire for valve amps. I have a lot of valve amps and a desire for money.

[quote name='REDLAWMAN' timestamp='1333804599' post='1606730'] Thanks, Dad: they both look really nice, the first one in particular. Croatia, though...?? [/quote] Closer than the US.

[quote name='AMPEG' timestamp='1333803691' post='1606718'] So in essence the drivers although having twice the wattage of say a single 12 are only moving the air of one...meaning they are louder but not as punchy? [/quote] Bassier/lower for a small box. A single 12 in twice the size box (actually maybe 50% bigger because no space taken up by the other speaker, gap and extra port length) will sound the same and have same max volume. Obviously you lose some power because it will be higher impedance than two speaker in parallel, but the extra power is wasted anyway because it isn't going into moving extra air in the isobaric box. For the cost of twice the price and extra weight, you gain a 1/3 smaller box. Edit: So for your purpose, the problem isn't lack of power as much as lack of volume, you need more speaker area moving air for your power to be better used.

[quote name='AMPEG' timestamp='1333803087' post='1606703'] Don't understand 'dual motor' How does an isobaric 212 differ from an ordinary cab? Also to run 2 x 8ohms cabs should i be connecting them via the two speaker inputs on the reverse of the amp rather than connecting the second cab via the dual jack inputs on the reverse of the speakers. [/quote] Isobaric means one speaker in in front of the other, the airgap between them is of static pressure, which is what 'isobaric' means. It means the two act as one speaker but with two motors, they sink twice the power but move the same amount of air as a single speaker, the upside is you can get away with a smaller box behind them as you have twice the power to expand and compress the air 'spring' in it, smaller cab is harder spring, larger cab is softer spring style.

When they say 'matched', did they say what was matched, how closely matched, and under what conditions? If they don't, doesn't really mean a lot.

What head? Describe signal chain. Tweeter in cab?
