VHT Special 6 git amp no power

offshore Champ knockoff with a few changes like a pull boost,

no sound,  looks like this, 10 inch speak,

it has a chassis,

another shot,

had a bad Chinese 6V6, so we put in a Russian 6V6, better red than dead, 

schematic with voltages,  has Triode/Pentode switch which places the screen to the plate or to a tap on the B+ supply,

do a repair without bootlegging the xfmr?    never!

15/16" tongue on the 93 EI lam, only other place we have seen this is on the Fischer 100 OPT ,

nice sounding lam, 1/16" shorter tongue than the popular 100 EI, 

butt stacked for DC,

scope shots of sq wave response and overdrive waveform,

how does it sound? loud with 10" speak, nice practice amp , has ext spk jacks for clubs,

Looks like a nice enough amp ,the point to point wiring I was surprised to see in there ,plenty of scope for modding.
I added a triode pentode switch on a peavey Nano valve I have ,it also cuts in and out an extra resistor on the cathode to correct the bias in the two different opperating modes, 1.5 or 5 watts . Those Chinese tubes are a false economy ,the surplus Russian mil spec stuff is great value for money.Great idea to keep dossier of all the transformers too.

I managed to fluke a repair on a big beast of a hiwatt 200 I got years ago ,one side of the primary was cooked ,as luck would have it ,the arcing was at one end of the final layer of windings and a little black hole in the outer insulation gave away the location, lent it to a good buddy of mine to use as a bass amp for a year ,he swore he never had a better sound before or since .
