Music is my first love and it will be my last. Music of the future and music of the past. To live without my music would be impossible to do. In this world of Johnson, Sunak, Truss, rip off energy companies, climate change and complete utter bastards, my music pulls me through.
nice poem if somewhat plajurised, lol.
I have my ear buds in listening to my ITunes driving between jobs and at the gym. Until the music dies…. Miss American Pie.

Been tying up a few loose ends with the amp in time for Owston. The 14 year old Maplin 100K volume control was playing up, so that has been changed out for a 25K Allen Bradley job. I did a final measurement of the voltages. All seems well. Zero hum and a lovely overall presentation.
The sound had deteriorated markedly. I had had a hearing problem in the right ear, but even so, I knew the sound was not as it should have been: fuzzy as feck. Anyway the change of pot cured the fuzziness and some ear drops over a few days, sorted the remaining problem in the right ear. So... we are all set. Looking forward to playing it at the venue, which is not something I would normally be confident about doing.

Forgot to mention that yesterday, I also recapped the first stages of the power supply (the two Cs in the CLC setup.)
The existing caps were 15 years old and at the rate my mate had been using the amp, those caps had had over 87000 hours of use!

Have you seen that Brimar are making EL34’s again? I dont think true pentode EL34’s triode connected will give much away to 2a3’s. Their price is very fair.
My first experience of home made single ended triode amp was with my friend Richard Warwick of timetec, the guy who made his own style of plasma speaker.
Ill never forget that wanderful experience. EL34 triode is tonefull. Yanks always prefered beam tubes. I like 34’s and 84’s more.

I have to agree with you there Paul. EL 34s just sound ‘right’ to me. I always seem to come back to them. Triode strapped with GNFb, they are simply brilliant. I think I’ll just stick with them.

Sadly I think their website is mainly future tense hopes. I think they are reselling valves manufactured elsewhere. I may be wrong, but can see no sign I am not. Their tag line is "Working towards UK valve manufacturing".
However they are all to be applauded as they are still it seems working towards actually making something. Looks like they have successfully made some type R triodes.
Whenever an honest man discovers that he's mistaken, he will either cease to be mistaken or he will cease to be honest.
The amp is now on its third fecking volume control.
The Allen Bradley carbon track pot became intermittent on the right channel yesterday afternoon, so now it has a TOCOS pot with poor channel balance as it’s all I have left in the spares box. Sometimes, using 50 year-old shagged out knackered bits and bobs is false economy. Anyway TOCOS pots are at least a known quantity and are reliable apart from the known channel balance issue at low levels.
