Time to sell off some NOS DHT and other tubes

I have used the 1H4g, 1H5gt and 1J6g and CX340 in line stages. Even seen a all DHT amp with 2X 1H4g driving a 300b

I would like to sell as a lot, great deal at $125.00

Everything arrived in great shape and well packed. Thanks!

Can you post a pointer or two to the circuits you tried w/the 1H4G and especially the 1H5Gs (I assume you just used the triodes w/o the diode)? Would be interested to study....

Do a search here and you will find several for the 1H4g and check out VT52.com. I first used batteries for heater and bias, but switched to a DC reg and cathode bias. Yes I did not connect the diode section on the 1H5gt and set up per the data sheet.
