Yeah back to the lead side last night, I see what you mean. At about 2 all you get is the edge, dial it up to 'bout 6 and in comes the blade and hilt. Not horrendously louder neither.

No, shouldn't be much louder. Labelling the controls "Volume" on non-master-volume amps really is a bit of a misnomer in present-day context - in terms of their function in the circuit, those controls are gain controls.

I removed the engine last night, drawing closer to going in for the master volume mod. What a fine looking thing it is...

I'll second that. Totally impressed with the work of all involved.

I daydream about making something like this but that's probably as far as it'll get (I used so much solder on one volume pot the other week I managed to weld it open).

Very cool anyway. Some soundbites would be nice. :thumbup:

Thanks, yeah I daydreamed it into existence, I'd forgotten what was hidden in that combo, must carry it out into the sunlight for better photo op. Wondering about boring a hole in the middle of the ventilation louvre (cement a washer either side) for the master pot. See what the boss says I guess.
Certainly got to be brave to crank it up enough to capture the magic for any kind of recording.

In my mind this is the auto version...

Not gut shot in here, I noticed - so here's a wee one:

Essentially the stock '68 circuit, with a couple of my own tweaks to layout, grounding scheme etc.

Eno/calling card made my life a lot easier by making it so that I had drill/ream/punch/deburr almost zero holes in the chassis (only small holes dictated by my custom layout).

Everyone should experience an NMV 50w at some point - I'd liken it to a good medium rare Scotch Fillet - charred on the outside, a bit bloody on the inside, and the right kind of greasy.

Every time I see one of these threads, I start lusting after a JTM45/100 again.
