On top of that, buying replacement output transformers from other makers, that do not follow the original design, the tone, quality and taste of the original design is lost, or deviated further away. Worse is that some of the original designs / schematics do not specify the primary/secondary winding in detail where it is impossible to remake.
Well, we have good news for you. We've repaired many famous and legendary output transformers in the past. We've reverse engineered it for our customers, kept the design data so that we could reproduce the same exact copy if future customers that want to restore or rebuild their classic machines, using the original cores, or with modern cores.
A few of them are Marantz 8B output transformers with the feedback secondaries, or WE 543A input transformers and etc.
Let us know what you need and we shall check if we have it for you.
Do note that we do not support piracy. We do not clone modern designs for profit. These are just for restoration/repair purposes only, or for extinct and out of print designs only.
