Hi

The piles of this are hidden under the piles of that which are somewhere behind the boxes of those….

With OCXO’s on the surplus market at < $20 sort of prices, fiddling with a TCXO may not make much sense. That goes double if there is also a lack of measurement capability. Buying a $150 GPSDO and a $500 counter only to check your “I saved $15” TCXO is probably not a bargain, or a good use of time. Even a cheap OCXO is likely to blow away a “worked over” TCXO for stability.
