I have found a Dynakit Stereo 70 amp, two Dynakit mono preamps, a DSC-1 stereo adapter, and a PS-1 power supply. The DSC-1 allows the two preamps to work off a single volume control; the PS-1 allows them to be powered without having to be connected to the amplifier.
These items are untested. The power cords are brittle and everything is old.
The ST-70 has the original Dynaco by Mullard EL-34s and GZ-34 rectifier. The 7199s are RCAs. I do not know what is in the preamps. They require a lot of disassembly.
I have done some price checking and it appears that what I have would easily bring $650 on eBay. In fact, I cannot find any sale of the PS-1 so its value is unknown.
I also have an Eico HF-61 preamp. Same story on the tubes.
And finally, a pair of Olson Golden Classic AS-733 speaker kits. Each kit includes a 12 inch woofer, 5 inch mid, and 2 inch tweeter, plus Danish made crossover. Each kit is complete with instructions. The newspapers used for packing these items date from 1962. You could have set built in time for their 50th anniversary.
If anyone is interested in any of these items, give me a call. Thanks for checking out my ad.
