Building a Dundovic tape playback preamplifier

Thanks for your list, I'll print it out and use it to search on eBay. I have the Kind of Blue tape, I was buying some used records at a shop on 31st Street in Baltimore and as I was paying I saw this tape. I asked about it and the owner said, "you can have it, nobody's buying tapes any more". Of course this was a few years ago before the recent interest in certain ones. I see them selling (or asking) for around $500.00.
I too, have more 2 track tapes than anything else. I started collecting them along time ago, I even bought a tape from J. Gordon Holt in beautiful shape for only $80.00. At the time I was guided by a tape enthusiast named Rich Brown who advised me to find a high speed 2 track Revox A77. I bought one off of a retired recording engineer and that started my efforts to refurbish tape recorders. He also sold high quality copies of safety master tapes and I collected them as well. Then he recommended the Stellavox SP7 deck which I bought from another collector named Charles King. At that time The Tape Project started up and collectable tapes began spiraling upwards. So, I found myself trying to find a way to get the most from 4 track tapes which had more recent (a relative term) artists.
Thanks agin for your list, it's good to know another tape enthusiast.

That's very cool that you got Kind of Blue for free. I paid $300 for the 4-track version in May 2022. It has gone for as high as $424 in the 4 years I have been tracking prices. The 2-track version has gone for as high as a whopping $1034! Prices went crazy during the pandemic, they've now cooled off a bit.
