justinsweber Posted July 28, 2014 Share Posted July 28, 2014 Reaching out the the brain trust... Ive seen NOS valves posts on EFB. Has anyone applied the EFB mods to larger amps? Is there a sperate EFB standalone PCB floating around yet? Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted July 28, 2014 Share Posted July 28, 2014 (edited) Justin, is this what you're talking about? http://www.tronola.com/A_New_Look_At_An_Old_Friend.pdf What is your goal in implementing such a modification? It may be more practical to simply design a power supply using a choke input filter which will provide more than enough regulation imho.

justinsweber Posted July 28, 2014 Author Share Posted July 28, 2014 Long tube life, more linear, more output... all the good only some of the bad. I emailed Dave... apearently its been done with upto 200watt monsters. He has a generic PCB for bringing EFB to almost any amp, but is not ready to release it. I generally like things simplier (few parts), but Ive wanted to try this out for a bit... Wondering who has tried and what results they achieved.
