Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: 45 tube filament repair




I went through about three or four iterations of parts changes over the past two months, before I got it as I thought it should play and should be. Now, its much FUN to hear. Journeyed from multiple bypassing with Wima MKPs, to REL RTs, to DynamiCaps, and to Teflons, and then to mixtures of vintage and new bypass caps.

What a huge undertaking. Fifty seven caps in a Direct Coupled 45 amp, film, no electrolytics, all selected by ear !! I am exhausted.

Though experimenting and attentive listening, I also LEARNED much about the total importance of, ( and how to better wire ) a S.E. amplifier, which we can not find in any book, nor on-line.

So, all in all, I am pleased to have worked on this new project!

I have had the Teflons breaking-in, on AM radio music, into power resistors, 7-24. Attached photo is closer, ( but not quite finally ), where I ended-up. Thanks for asking.
