Hello Bob,
If you frequent hamfests, you can find some good buys on tubes. I purchased
a
4-1000 a year ago for $25.00. I purchased an RF deck from a ship radio with
a pair of 813's for $25.00.
So if you have patience you can find some good buys on tubes. If in a hurry,
you have to open your wallet.
