Re: Which transformers for amplifier
I too really liked the sound of the Heyboer ( prices are great too) I put in my old Plexi RI. It was a nice improvement over the stock Drake that was in there. I know many folks the love the MM, they are not alone as far as quality, current, iron goes. Cerrum from the Plexi Palace forum builds his own plexi vintage spec transformers. Those that have them have raved about the sound they get.
On the old side, I love the Hammonds in my Traynors. FREAKIN HUGE!!. Partridge are legendary and are a huge part of the British Voice. My Carlsbro has the same iron that Plexi era Marshalls used. I paid 275.00 for that amp but could sell the transformers and choke for likely double the price of the amp. ( A guy I know got close to 700.00 for his) Original, working Iron is worth a lot of cash.
There are lots of quality options for builders out there, tis truley a great era for amps right now. All those vintage amps have made for new builders demanding the same quality in new parts, and builders are listening.
