I have been getting more and more interested in vintage type Marshall amps lately. I have done a fair amount of research and tried to listen to recordings and demo videos, as well as learn what specific Marshall models from the 1960s ( the era which I am interested in in regards to Marshall tones) were used in specific recordings which I like the specific tones of that Marshall which was used in that recording. I love all of the various different Marshall tones from that era but I realize that I, right now, am most attracted to the JTM 45 and the JTM 45/100. I would love to be able to afford either a Germino Classic 45 or a Metropoulos JTM45 but they are rather out of my price range currently... as lovely as they are. I have learned some about the Rockitt Retro amps and they seem to be very well made and use the best components, similar to Metropoulos and Germino. And I understand that up to just a few years ago Metropoulos offered the amps that George now builds, in kit form. But that the kits are no longer available from Metro amps. And although Rockitt Retro amps seem like a great amp for the prices ( between $1000 and $1500 range)... he does not offer the JTM45 model specifically. So... looking on Ebay, I see at least a couple of builders who offer various builds, the JTM 45 included... and are using high quality parts and Mercury Magnetic trannies... and the photos seem to show good worksmanship. (But then admittedly I do not know electronics very well and am not a good judge of the electronic worksmanship of hand built amps). Those two builders, that I noticed on Ebay, were Slingo amps and Carl's custom amps. I was wondering if anyone here had any suggestions as to builders, possibly who you have bought an amp from or know about personally, who build the JTM45 with high quality parts /and trannies (like those used in Metro amps for example) and do a great job of building. And who sell their amps for around the prices of the Rockitt Retro amps. Thanks for any suggestions.
