Re: Filament bias and PP DHT

Hi Andy ,
I'm not too sure about the 1635 now , I'll probably go for the 1635 5mA , the 46 has nice low Ra so should be ok with the lower inductance of the 5mA version . How many type 46 did you buy , 100 ? ;) Your amp sounds nice but why not split the filaments ? I'll be doing my amp 4 box , 2 psu's on sand box plinths , 2 power sections on top . It'll be all DHT too , no IDHT as concertina valve this time .

cheers
