that TT OT has 2200ohm so it's ok for 6L6 , for EL34 you need 1700/at least 1900ohm primary.

I use Heyboer irons, great TONE!!

Hi Franco, It depends on how you want to proceed, IMHO to set the trimmer of the phase inverter, you should have the final outputs perfectly matched in terms of transconductance, and an excellently made output transformer! otherwise the adjustment makes no sense.

many guys here adjust it , by ear!

I think among the first models produced, circa 2009/2010

I have the schematic of the signature reverb type 1 and it's a bit different.

The NFB 4k7/100K net res. what OT tap should it be connected to?

4 Ohm?

I have already contacted NTE support and they told me that the new productions (item on the right) are the same as those with the blue casing (on the left) but this does not seem to be the case!!

so I buyed MF resistors and received Mox

power scaler is the best solution! IMHO.

At mouser you can found vishay resistor 1ohm 1% 3w

Correct!, but what do you mean by POWER SWITCH GROUND?

beautiful build!!, congratulations for all the components used, I assume that you have done a great research. very good!

Nice work, very clean build! congrats

Hi, I'm looking for faceplate and rearplate of Fender blackface or silverface era, Bassman or bandmaster.
There is someone who reproduces these plates, or if they can be purchased on some site.

Thanks in advance
Sergio

Bassman PT / OT for a 50w

Hi , nice build! congrats!

About the 50/100w switch , work fine?

Hi , congrat for the build.
If you have a good twist AC rail , I suggest to check all the PCB board solder ground joint. And re-adjust your lead dress

Sincerely. I don't like the pcb for this type of amp, but that's my personal taste.
