Whoops I was disconnecting the transformer secondaries from the board and one of the spade connectors pulled straight out of the pcb.Refluxed and rewetted/soldered I connected things back up and the realay clicked;led lit and I now have +- 14.5v and an offset reading which has been steady at 4.8mv with the input shorted for the last 10/15 mins.

Did you solder both sides on all those tabs as in post #13 of this thread? It may seem excessive but it isn't

I did Bob yes.Strange that I had connected/disconnected umpteen times before with nothing coming apart and what appeared to be shiney solder joints.Anyway the board is still connected with 4.8mv offset and nothing overheating.Would I be better to try with a dummy load?

Good, Your load question is above my pay grade. Andrew or Darly can answer that.

With such low offest you can safely attach speakers, IMHO.

Thanks Dario. The concept might be more appropriate for transistor heaters like the N.Pass F series but it's been fun to work out. More to come in a few days.

Hi folks.

Unfortunately didn't have much luck trying to get a Ref.C kit from Linuxguru, so am very interested in this Freman edition, which looks like it could sound even better?

Are boards still available please?

Cheers,

John.

Sadly no, maybe you could ask if one of the Release Candidate partecipants that buyed spare boards wants to sell them.

In the next months, though, there will probably be a group buy.
