The advice at B&Q was not to use a rattle can but furniture paint as they felt I'd get a better finish. 4 coats later, it's okay. From a distance. It doesn't seem to be particularly resilient though. . 20231102_125107.jpg . With cheapo magnetic computer vents to allow ventilation. . 20231102_125...

I took my MoFo (and D3a-2A3 SET) round to Bostod's earlier this morning, dodging the heavy rain. And I realised I never posted any photos of my "proper" build. There were a few MoFo threads at the time, I think this was the one I piggy backed, so I'll bung them here. This was a cheap build...

Interesting stuff Paul. I woke up this morning thinking about a low voltage 26 direct coupled to 45, but this is a very different direction. I need to study reread your posts when I have a bit more time, but I don't have any 10k OPTs, only 5k, so might not be a goer anyway.

Not awfully compatible with random drugs and alcohol testing at work sadly

Yeah yeah, I know. :-) But sometimes things just sound better. I'd quite like to try a 26 driving the 45, but that gets a lot more complicated. I'm driven by detail and openness - yeah real hi fi words. Dont ask me to explain that! But this helps me make more sense of the melody, and pretty much eve...

18 months ago I built this amp - time flies. I haven't done anything to it in that time except enjoy it. Marvellous. I keep meaning to box it up but then have nagging thoughts that I could make improvements. Improvements might just be differences though... The old article from Sound Practices includ...

Ah yes, good to see you're over the worst

Ah I see.

That's very light for mahogany.

Impressive. In a way it's a shame to have covered up mahogany, but the maple looks great. I take it the body is flat rather than gently curved?

A big lump of mahogany can't have been cheap? Is it preferred for guitars, or just something you had laying around?

Nightmare Steve. Glad you got away okay Steve.

to JCLPCB. And others like PCBWay. It has to be very simple point-to-point now for me to bother, it's easy enough, and satisfying, to draft a PCB. And so cheap.

I'm interested in your veneering technique when you get to that bit. I haven't done any yet but must try sometime.

It's slightly concerning Steve I must say, I use them in the GM70 amp

No they're good points. I was thinking earlier how different the amps are - whilst they're both SETs they're quite different really. I don't remember the bass being compromised switching to the 45s, but I was using class D with the GM70s too as I'd found the passive crossover robbed life and detail....

But today if I wanted better bass I would follow Simon. There is no longer any point to building a valve bass amp. Last century the place my head was. Valves could do no wrong. But my single amps do kick out enough bass for my requirements. Quad 57’s are wide band enough for me and el34’s at 6 watt...
