Members Zhorellski Posted February 5, 2013 Members Share Posted February 5, 2013 Couple of novice questions regarding VHT 2/50/2poweramp; -Safe to use mix tubes 6L6/EL34?-Does it come with bias pot?-How does it sound low volume (condo) will it loose low end?-Will 6v6 tubes work? Thanks inadvance! Link to comment Share on other sites More sharing options...

I use mine a couple times a week. -Will 6v6 tubes work? - don't know The inability to switch power tubes has something to do with the circuit, per Steve Fryette. He answered in a forum post a few years ago, not sure which forum. The sweep on the bias pot doesn't go low enough to accomodate 6L6's. Bob at Eurotubes disagrees. He says he can provide a set of 6L6 tubes that will work fine, but I haven't tried it. Link to comment Share on other sites More sharing options...
Members Fryette Support Posted February 6, 2013 Members Share Posted February 6, 2013 This amplifier will not accept 6V6s.You can install 6L6s with a bias circuit mod, but like all tube amps, only one type will provide the correct impedance match for the output transformer. Since that relationship determines dynamic range and power output, only EL34s will produce full power. Eurotubes may represent that modding the bias makes everything compatible. Not so. That only adjusts the idle current, not impedance. For more info see: http://fryetteamps.wordpress.com/2012/10/09/power-tube-switching/ Link to comment Share on other sites More sharing options...
Members Zhorellski Posted February 8, 2013 Author Members Share Posted February 8, 2013 Thanks for all the inputs! btw, when is your 1u power amp coming out? looks and sounds amazing on youtube! Link to comment Share on other sites More sharing options...
Members Fryette Support Posted February 9, 2013 Members Share Posted February 9, 2013 Thank you. The LXII is in production now. First delivery date will be announced soon on http://www.facebook.com/FryetteAmps Link to comment Share on other sites More sharing options...
Members Superhooker Posted February 12, 2013 Members Share Posted February 12, 2013 Yep, and its a beast.This poweramp is so good I cant picture myself using anyrhing else for a power section.This truly is a piece of gear i will never sell. My whole sound and rig builds around this thing.Reliable, powerful, super flexible and it sounds absolutely beautiful at any volume level. Link to comment Share on other sites More sharing options...
Members timrocker Posted May 24, 2013 Members Share Posted May 24, 2013 I just got a VHT 2/50/2. It's loaded with EL34's. I'm loving it. I do need to look at some cooling/ventilation remedies. I live in a very hot climate, and am running it class A. Any tips? Thanks! Link to comment Share on other sites More sharing options...
