Hi, needs some help and hoping people can help. Looking to do a 6L6 black vibe build. i have a 125A29A transformer instead of the 125a7a thats on the layout. Will this be usable? or will i need to change parts from the layout as designed? https://robrobinette.com/images/Guitar/AB763_Models/RR763_BLA...

thanks for the reply,

what has the difference been in sound?

what other transformers are compatible with this amp. twin reverb, bassman?

was wondering what transformer upgrade people have used for their 6L6 dlite amps

Hello, please excuse my ignorance but I'm not sure what you are refering to by values on the plate load and cathodes? Could someone help me with what I'm looking for.

Hello, i've been compiling parts for this build and am having truobles with the filter caps. With the layout I have now, I will be using two 200uf cap in series with 330k resistors across them.
