Re: NOS NTE metal film resistors
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

fender faceplate searching!
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

Re: Steel String Singer #002 Build - Noise Problem
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.

Re: ODS 4x6V6
IMHO the real D sound comes out of a 100W, ... this low wattage ODS can be a good compromise and useful in small spaces, at home or in small situations.
I have some 100w 6L6 and EL34 100w both, but this 36w I like how it play. 6V6 can be a great tube!!
