Just to mention - Fg810 is running fine, it's on all day every day, if not streaming music then audio for videos and DVD's. Ditto the Kubelic DAC is cosntantly on for music. I have been repeatedly running a big iTunes shuffle playlist (about 2.5 days' worth, so far :D ), heard it all before natch, s...

If it helps - still using FreePCB - can import netlist from LTspice (with a bit of editing of the netlist file). Latest version(s) Gerber files are compatible with JLC PCB (a nice discovery).

+1.

OK next silly question, why 4 Watts

PS: 2 matched EL84 may bias together, but unlikely to stay matched with use (my personal experience).

Yups, ta muchly.

PPS - just realised it goes right past a cafe that used to be Reepham railway station, know it well.

Looks at a map for Marriott's Way, a-ha right 'cause I was in that area last year. On the radar.

Thanks for that, I have various sketchy plans for summer, cycling might be involved at some point. But also motorbikes, sidecar outfits ... too many irons really :lol: Reminds me I was looking at The Viking Way recently, but Google images suggest some sections are blocked off or otherwise inaccessib...

Just IMO, I don't like the idea of 2 x EL84 in parallel, seems like a step too complicated. Also getting them biased the same with fixed bias couild be a headache. So then what, separate bias circuits with trimmers? I assume the issue is must drive a 2.5k primary? Why can't the secondary load be alt...

I like the holding stand thingy!

Been a bit of a saga - I was just going to mention, but you changed it - the fading away thumping noise on switch off suggests low frequency oscillation. But not sure how. Could have been the PSU doing weird things, and amplified by the o/p stages. Just guessing.

Sorry about that Phil.

Thanks very much. I have champagne and chocolate cake, so pretty good.

You noticed!

Actually it was a couple of days ago, I'm only writing it up now.

The stator pole ends are pretty beat up, and the inside of the rotor has score marks. Going by my previous experience with my old D3, this indicates that the left crank main bearing had 'collapsed', allowing the crank end to 'whip', which in turn allowed the rotor and stator to come into contact. Bu...
