I have four vintage Tektronix plug-ins from the W0ZUS auction. I have no need for these plug-ins. They are all in good to very good condition and appear to be complete and unmolested. The ony exception that I can find is that the 1A4 plug-in is missing a front knob. All tubes are in place and will be included. Here are the types:
Type 1A1
Type 1A2
Type 1A4
Type 53/54C
I do not know if these units work. I also don't know what they are worth. I'd prefer to sell as a lot. Make offer.
Thanks, Ron W8ACR
