Techs, how hard would this be?

And I have a feeling the answer is, not very hard. Couple a 20 watt power supply with a 1959 SLP preamp. By comparison to a 100 watter, I know they won't sound the same, but just how different will they sound from eachother?

Power supply or Power Section?


In a power section, the differences will come down to type of tube used and B+.
The difference will obviously be less headroom, and probably more forgiving than a 100 watt SLP.

I think you'll need to say more about your plan. I believe if you simply put in a 20 watt transformer, you would kill your tubes. Do you mean replace transformer and tube type? Or just run the preamp into something else?

One quick way to try this is to install a pair of THD Yellow Jackets into a 1987 Marshall. Instant SLP with a 20w power section.
