Those Dyna PAM-1 preamps can still be purchased one at a time for less than $75. each; sometimes with two Tellees hidden inside. The Dyna PAM actually gave the Marantz 1 mono preamp a run for the money. Simpler circuitry, less tubes, no cathode followers, but less versatile than the Marantz 1, Dyna sure knew how to satisfy on a budget.The PAM had three phono EQ positions, which the PAS should have kept IMHO, grid stopper resistors at the phono input tube's grid, decent EQ parts and values for the time, plus that cathode to cathode "positive feedback" resistor that many, many classic units and even more modern preamps have kept. Many CJ preamps after the PV-2AR, until they later decided to use passive EQ, also used that K-K feedback R. That is saying a lot !
The Shure M65 as well as the Shure SE-1, the transcription studio grade phono preamp also uses this technique. The SE-1 actually has Dynaco PAS type PC boards inside, but the EQ can be tweaked with air gap tuning caps, along with a simple 12AY7 line out stage using of all things; a UTC A series Plate to Line Output tranny. With this hobby, popularity is not important. Most important, to us, is the playback enjoyment factor. It is really all about playing the records and enjoying the listening...
