Hello- I thought I would ask if anyone on the list had these parts for sale: 1. To repair a Ten Tec #255 power supply: I picked one up and it was missing the entire regulator board #80567. I need this regulator board. 2, To repair a Ten Tec Argonaut 505: I need the small knob for the preselector (upper left corner). Thank you, Byron WA5THJ.
