Why do you use MF, metal film resistors for the grid stoppers?

My trainwreck express is done, a few esthetic details missing, cab, chassis, turret boards are all diy the sound is really great, touch sensitivity is very good, a monster headroom in the clean sound.And it is quite.But too loud to hear the overdrive spot.

I have the same goal with a finished train wreck express .
Vintage OD at low volume.Can you please share a schematic (with mod)

Many thanks

Hi

I have plenty of 220 nf (0,22uf) 400v, axial.pm me.

Hi Is someone knows the ref (the primary impedance) of this transformer OT 3 output 4/8/16 ohms,installed in a 60 \70 ‘s guyatone tube amp ,it’s seems it’s not the original one , circuit close to an AB 763,I found it with some el34 and at max a very low bias .Many thanks . https://www.noelshack.com/...

I m not sure if it is ,or not the original OT...

Port city 1x12”with a recent celestion cream back closed 8 ohms or a eminence Black window style ,125w with a big coil old one from my Mesa boogie mark 2 (1979) 8ohm There is a new OT on the amplifier 8 and 16 ohms ,no reference ,any idea ? https://www.noelshack.com/2018-03-4-1516299095-a0303115-ddc...
