CLONE 6G2 PRINCETON BY TOBY TRAYLOR

This is a copy of the 6G2 Princeton circuit. It took me a while to get this one right. The Chassis is from Mojotone. Unfortunately, the current chassis sold by Mojotone has a power transformer cutout for a low powered 5E3. So, I tried using that transformer set at first...and it did not work. I wound up buying a Mercury set specifically for the 6G2. It was too small for the Mojotone chassis but when I turned the transformer 90 degrees, it had enough space to fit with new screw holes for that orientation.
Secondly, once the amp was completely assembled, it had an oscillation issue. After quite a bit of searching, I found the oscillation was coming from the yellow lead going into the screen of the first half of V2 (12AX7). Once I found it, I redressed the lead closer to the body and the oscillation disappeared. I will probably go back in and put a shielded cable in the place of the push-back wire and run it under the eyelet board.
If you are considering an amp like this, I would suggest going with the correct transformers for this schematic and reorienting the PT and OT. The version that finally worked for me was the original Fender schematic. So, I would follow that. I did run a twisted filament pair for modern grounding and used a grounded power cable. Of course, bypass the death cap. You may see where I modded the rectifier tube with diodes, but I wound up removing those...In fact, I wound up pulling this amp apart a couple of times...hence the parts and eyelet board shown in a box...but the final result was a beautiful sounding 6G2 amp...and it was WELL worth the initial frustrations.
Finally, I mentioned Mojotone a couple of times. I spoke to a representative from Mojotone and he explained that the chassis' were ordered, in bulk, by a customer that wound up not using the order. I think Mojotone is a great company. I order from them quite often. I just want to make other builders aware of the issue with the transformer cut out. Not a big issue if you don't mind altering the chassis, but possibly a big issue for builders who aren't comfortable with making alterations.

Don't get me wrong. I am not criticizing.
It's just that some choices made me scratch my head. My conclusion was that most probably, you have used whatever parts you have had at home.
Some parts are best possible, and the others are reasonable, and some are questionable.
Like resistors. Sure, everyone uses different types of resistors at different places, but choice where to use what type is made my OCD spike. Like metal film on plate resistors and carbon film as nodal resistors and then few random carbon composition resistors?
Like TAD first filter cap, but then I can't tell what the two are next once. Then relatively expensive Jupiter in the biasing circuit.
Mallory 150 series caps sound and performs well and are priced good as well.
Benton tube sockets are the same. Good performance fir not yhat much money.
Overall, it's not bad, but it's confusing for me.
BTW, there are power transformers that are just taller and fit perfectly in 5E3 Chassis and are meant for upgrading 5E3 to two 6L6GC tubes.
I would go with metal oxide nodal resistors and possibly keep the rest of the resistors on the eylet board as the carbon composition resistors. Or carbon film. Or as third choice metal film resistors.
Carbon composition resistors give that vintage vide as plate resistors on the preamp tubes. They are a bit finicky and more noisy but have that vintage tone.
Everywhere where it gets hot or resistors are stepping down the B+, it's hard to beat metal oxide stability and durability.
Having metal oxide screen resistors is a great choice while they are on the sockets and get hot but provide just positive voltage to screens. Metal film grid stoppers are also good choice there on the sockets of the output tubes. Someone might argue they sound different. The option is to relocate them and use "better sounding type" on wire leading to the sockets.
So my conclusion was you have had parts on hands and used vest you had to build as nice of the amplifier you could with that.

Wow, that's some feedback there. Thanks man, I appreciate your input.
