[Amps] Thermal Delay Relays

[George Knight]

Have a quantity of NOS Amperite model 6N0180 units in original unopened cartons. These relays operate at 6.3 heater volts and give 3 minutes delay. They fit into a standard octal socket.
Will sell 4 for $100.00 U.S. or Can. or individually at $30.00 ea. plus postage. I will pay postage on quantities of 4.
Payment to be made by money order only. My address is as follows:

                                   N7A 2G7
Hoping these will be used in a Linear Amp now being planned.
