Modifying Amps to Vintage Specs.

Not much of a sparky beyond some very basic tinkering.

I've played through a new production model Fender Deluxe Reverb. It's a very fine amp.

If I were to buy a new one, what would go into making it "more like the old ones", so to speak?

Is it as simple as swapping for period correct components, or are there fundamental voice differences in today's amps?

I'm saying Fender as an example, but I'm thinking of all amps as well.

ST20C or Origin 50C

Does anyone have experience with the Origin 50 combo and what the circuit is like or based on?

I recently got a ST20C and I like it but it doesn’t have quite enough headroom so it’s a little more distorted than I’d like at stage volume. I started looking at the Origin 20 and 50 and those have a master volume as well as DI out and a Creamback speaker. On paper, it’s what I’m looking for but I don’t know much about the circuit. Are they based on the JTMs? I’m also looking at the Friedman Runt 20, but it’s more of a 2 channel amp and pricey.

I play alt-country and mostly play fairly clean rhythm but also trade leads. The ST20C handles boost for leads very well and the cleans sit well in the mix, but it starts getting pretty gritty pretty quick.

EVM12L alternatives for 180w Super Twin Reverb

Hello! I need new speakers for a Super Twin Reverb that I picked up for a steal on marketplace, and then proceeded to dump more money than I paid for it in replacement tubes ($200 compactatron tube, the fuck is that...)! So yeah now I'm in too deep, can't stop now. I'm thinking I want to go the EVM12L style speakers because of course the ones i have in there are toast. Anyone got experience with these?

• WGS12L

• Eminence Delta Pro 12A

• Eminence EM12 / EM12N

• Weber Michigan

Or should I just go with the real deal? Weight is not a concern, this thing is already unforgivably heavy and I don't plan on moving it much.

Chasing vibration/buzzing sound

I have a ‘65 Vibrolux and I have been through this thing a few times trying to find something that’s sympathetically vibrating. I notice it most when I let an E flat ring out using my LP in the neck position, volume at 3-4 range on the amp. I don’t hear it when volume is fairly low or playing single coils through the amp.

What I’ve done so far:

Replace all tubes except the 6L6’s and GZ34
Replaced speakers recently
Checked all hardware is tight including speaker studs
/nuts
Tightened Fender badge that’s affixed to the baffle.
Played the reliably offending notes and put my hand on various parts of the amp to see if I can find it.
Played through normal channel 1 and 2 and vibrato channel 1 and 2, the problem follows all circuits.

I realize without hearing it for yourselves, it’s going to be hard, but maybe there is something obvious I’m missing. The amp is very quiet (at idle) otherwise.
