Dynaco ST70 with yellow sheet mod and SS rectifier?

Hi All,

I have what I hope is a simple/easy question. I have an original Dynaco ST-70, of which I've replaced the selenium rectifier with a diode and done the yellow sheet mod on. I'm about to replace the stock transformer with a higher-powered triode USA version, to try out some KT88 tubes I have around. I've read that the KT88s both consume more power but also do better with a SS rectifier (or at least wear out tube rectifiers faster). My question is can I use a Weber WZ68 SS rectifier (with TDA) without having to remove the yellow sheet mod?

Thanks!
Pete

Yes, you can use tube or solid state rectifiers with the yellow sheet mod. You should have fewer blown rectifiers after the mod regardless of the power tubes used.

Funny, getting ready to build a guitar amp on the Fender 5e3 schematic. Doing research and, no surprise, there a million mods for these things. But, this is the only place I've come across the yellow sheet diode mod.

Great resource we have here! THANKS!!!

It's around but worded differently ... and it gets more traction here than other places I've come across. Cheers!
