I have an oscillator assembly for a COllins 32RA transmitter. This is a plug in frequency determining device with a 7000 type part number. Frequency coverage is from 2.5-3.4 mc in one section and 3.2 - 4.5 mc in the second section. Looks like it's in nice condition. It must be a leftover from my 32RA 15 years back. $35 plus shipping?
