Man you better fix that up an post some clips asap.
People are waiting for those. Grin

So relay is working but still no sound.
I'm not a tech but if I would be in your shoes...
Are the voltages on V2 fine?
Triple check the wiring... maybe you have a cold solder in there.
If all that checks out... maybe there's something wrong with the elements on the board (V2 part). Measure them...

If all that is fine... take it to your local amp tech. At least that's something I would do.

You did try to change the tube, right?

Your plate voltage is a bit low... but maybe that's right for BM amp, I don't know
On OTS V2 voltages should be around these numbers...
pin1 200
pin3 1.7
pin6 201
pin8 1.7

Hey, why don't you ask Nik, he will most certainly have some ideas for you.
...and let us know what happens... so we can all learn from your experience.

hello

yes its working
i have resoldered all contacts on the overdrive channel and now its OK
The sound is improving every day
i thing it needs a couple of hours to "burn in"
i was septic about this but in fact its getting better from day to day clearer OD and cleans

I'm glad to hear that.
I ordered mine as well... can't wait to get it.

If you can, please post some clips. I would really appreciate if you could.
