As with all these home brew projects, you are constantly re-evaluating the design and as Ivthink about the switch wiring, I realise that my thoughts were wrong. Bridging an amp (or more correctly amps) require that two or more power amplifiers run in anti-phase. One amplifier will drive the +ve terminal of the speaker and the other will drive the -ve terminal of the speaker. By doing this we double the voltage swing across the speaker and potentially quadruple the power available. In reality most amplifiers will be currently limited, that is that they will only be able to supply a given amount of power and in most cases That would limit the increase in power to a factor of two. Many of our favourite amps run bridged amps including the Ashdown RM range, Aquilar TH range and some GK amps like the MB200. Of course there is no such thing as a free lunch and the increase in power comes with several negative including increased distortion. Luckily in most cases this is minimal and still well below what we could hear. Tfe problem with the Kilowatt design as shown in the original wiring diagram is that the level or volume pots have to be set exactly by hand/eye to exactly the same level otherwise the distortion will rise considerably and one amplifier worked harder than the other. So I am now rethinking the wiring to take human error out of the equation.

The speaker connections are done and I have tried to tidy them up with some cable ties. The cable is quite heavy duty as it carries the most current. The mains cable carries more power but you need thicker cable to higher currents. You might notice that the RED Speakon connector has two red cables. That is for Bridged operation where the +ve connection from both amps are used to drive the speaker. Neutrik recommend that the 1+ and 2+ Terminals are used for bridged connection. This is to ensure that normal Speakon leads cannot connect to the amp in bridge mode. The thinking is that you have to know what cable to connect to get bridged operation but that installing a conventional Speakon cable would do no damage. The speaker cables should be twisted if possible but these are quite stiff and I can only get a couple of turns on them. Next to with up the inputs and switches.

Well done John and I am sure the lessons learnt are almost as satisfying as the combo itself. Many don't realise that the acoustic basses by Washburn were only produced to be used at MTV's unplugged series and of course they were amplified at the sessions by the FOH system, In my opinion they are almost useless without amplification and it does not have to be "in yer face". Just a little push makes all the difference. Well done.

I don't have any of these but would go for the Gnome for the following reasons. Firstly although I love the design of the Elf and it did create this section of micro amps, it is a higher priced for no obvious gain. Secondly, the Gnome has more power and suggests it could handle being pushed harder for longer. The power amp in the GK MB200 needs serious heat management to operate at anywhere near full power and that needs a bigger box. Add the fact that the EQ section is rather unique to GK and that would be out for me (I used to own a GK combo with effectively the MB200 amp inside). The Gnome now comes with a 4 year warranty, that is a double edged sword. It does protect you for longer BUT sometimes an extended manufacture's warranty indicates a product has had reliability problems, or is not selling well. I have heard nothing about the Gnome being unreliable but its worth keeping in mind. Markbass, seem to be a problem if something does go wrong and are extremely unhelpful if it does, so that is a no from me. I think the pre-amp pedal with DI makes a lot of sense to take as well as, rather than instead of a micro amp as you never know what FOH you will get.

True the humbuckers help but a standard tele, on the bridge pickup into a Fender amp? it is horrible, barely musical.

I would say that many songs I did grudgingly became my favourite songs.

Half decent but telecasters?

Snap, usually song 1 set 2.

Its a crossover song between blues and soul but has enough in it to keep a simple soul like me happy. I know a lot of musicians hate it though.

IAs you probably know by now, this project trundles on at its own pace. Today I wired up the amp modules to test that all was well. The protection lights for both modules came on and went off while the modules were settling down and a brief sound check on both was fine. As I was checking module B, I noticed that all the lights had gone out on module A. I checked everything But could not see the reason. Took it out and checked it out of the case.., all good but then when reinstalled it again was dead. Module A was the original module I bought and it has been on and out of the chassis, a new mains terminal block was fitted and it was the test module that has had lots of work done to it.I suspect it is something to do with the new mains terminal block. So I got my drill out, drilled mounting holes on the spare module and that is now installed as module A. The original module has been put on the “look at later” pile. All good now both modules working and now to start tha boring part, wiring. The switching arrangements are not that complicated but have added to the amount of wiring. I also need to make sure all the metal panels connect directly to earth. The black anodisation on the aluminium panels is not very conductive. I will take more pictures next time but it looks like a rats nest at the moment so that will wait.

In that enclosure I would be skeptical that you could get full power without active cooling via fans.

The 57-60 Les Pauls really created this one. However it is nothing to do with the age, the wood, it is the alnico pickups that slowly lost some of the initial magnetism giving a sweeter sound than a new humbucker.

Probably but they did some great songs.

Try telling someone that their ideas about tonewood are false......

The profanity filter changed my real word, that rhymes with duck into flip.

I do not usually swear online but for flip sake it’s a USB cable

Tylenol is basically paracetamol and generally considered ineffective against arthritis, however my partner believes in it and says it helps. She recently had a real problem with sciatica and was diagnosed Gabapentin. That made her sciatica a lot better but almost took the pain of her arthritis. However I believe this is a class A drug so not a long term solution.

70 too and would be gigging tonight but for the rhythm guitarist having Covid.

Probably not the iPads fault. The advice is always the same with the small digital mixers. Use an external router. I have had the problem with Soundcraft and Behringer mixers and have no reason to think that the M18 has a better router built in. I bought a simple TP Link 2.4 GHz router and it works fine and it works fine With my sound craft UI 16

Thanks for correcting me, I was a bit right. Incidentally it is common knowledge the Keith Richards has self medicated for several decades. I would repeat my warning about NSADs as my mum over-used Asprin and lost half her stomach in an emergency operation because of it. I use Pyroxicam on my fingers sometimes before I play and Voltarol ( Diclofenac ) gel if it’s really bad. However I don’t really suffer that badly and would agree that playing helps. If it starts early enough before a gig I just take Ibruprofen. I should stress though that although the episodes are becoming closer together, it is more than manageable for me. I had the op on my big toe about 10 years ago and I could barely walk before so I do know what chronic pain is.

Again I am not a Dr but in my experience Diclafenac is better that Ibuprofen but has that same issues. It is also an NSAD (as is asprin) and all have the side effect that if used unwisely to cause stomach bleeds and aggravate ulcers. You should take after meals on a full stomach to stop the tablet lying on the stomach wall. As for dosage. my daughter is a Nurse Practitioner. She tells me that the normal Ibuprufen tablets are 200mg and a normal dose is 400mg. However this is an average for adults and if you are on the larger side, you may need to got to 600mg. I have not heard of anyone taking more than that but I am not a Dr. A

That looks like Rheumatoid Arthritis, Osteoarthritis does not cause the joints to swell like that normally.

I had that and had it operated on about 8 years ago. It takes a while to heal but I have hardly had any pain since, despite the surgeon saying he was operating for mobility not pain

What sort of size, weight and price are you looking at?

I cannot tell a lie, I am not Paul Page, Rue Paul or Jimmy Page. I apologise to the OP for my comment and the less than helpful comments that have resulted.
