Post Subject: The new transformers for Super Melquiades.Posted by Romy the Cat on: 7/11/2007
It, looks like the problem with the steel chassis picking up stay magnetic fields from my Super Milq’s power supply is about to be gone. With the introduction of the 3 extra single-stage channels I needed more current for 6.3V filaments and slightly other voltages for B+…. I was thinking to make it in half-ass, using my current magnetic, but then, since it will me my last amp, I decided to go for the set of the new transformers. Sure, opening the Pandora Box I opened it wide open and eventually I went for a new set of custom toroids for everything, including the potted chokes and so on… Since they will be hanging outside of the chassis in L-brackets (like the bunny ears) it will be no more with-chassis talking….
