Just spotted the following on E-Bay while searching for heatsink material:
Spectra Communications 50 watt 220 repeater amp with heatsink, presumed defective (failed under intermittent operation). Being sold for heatsink value, but probably repairable.... Currently at $12.95 with no bids, 3 available. Ad says equivalent to Moto MX800? Item number 180173021724 Note: I have no connection with this auction: I just saw it and thought someone here might be interested. George, KA3HSW / WQGJ413
