I have a large supply of tubes on hand that are surplus to my needs. These are receiver and audio tubes. No transmitter tubes (rf amp) available at this time. The tubes are NOS, some boxes shelf worn. They are priced at $3.50 each. Any 12 for $40.00 plus mailing. Any 20 for $55.00 plus mailing. Send me your list. Thanks, Bob,W4WSZ
