Dom G	Re: 6v6 question Hi John, I recently bought a "supposedly stock" 68 princeton reverb thru the net. Turns out it has a diode rectifier, different pwr xfrmr, and GT6V6HD tubes. Out of curiosity I searched some groove tube sites and found at least one that states that this tube is a 7408. According to the RCA tube book, the 7408 is used in high quality audio circuits and has a filament current of .45 amps. Do you know if the 7408/gt6v6hd is the same tube, ie can be used interchangeabley? How can I find out for sure? How can I check the actual filament current draw. Thanx Dom
