Amplifone HV boards will be reproduced - info needed

that is a 12 pin one - I thought you said it was a 10 pin socket???

Nah it's 12 pin

While not exactly in line with your question, I have this repro one and it would be nice if your repro one was compatible with it (if I ever need another)

I wonder how they solved the regulation that the MCI does on that replacement board ?

Something else: Should "we" consider improving certain aspects of the design ?
I mean, with modern-day electronics it should be possible to get rid of the 50 ohms resistors and solve the lack of current that the 7824 and 7924 can deliver in a much more elegant way ? Just an idea of course...

Strange. All 3 of my sets are green.

Yes nearly all of mine are green, I'm not concerned about the component or wire placing just the colour match. Green deflection boards always seem to be in better (not burnt) condition.

I am happy to do the green version, All I need is excellent pics of all the parts side, where no components are hidden by wires or parts. So 3 or 4 different angles. Then I can compare to my beige board and put that to rest

I will let someone else get into the design side, I will simply be repro-ing it, with spots for 50 ohm resistors on the heat sink, spots for the diodes, and spots for 3 x chokes (MC1) or the original item, as Mike suggested, so people can choose.

If it ain't broke . . . .

I still need more hi res and focused pics of the green board please guys

I want to make the green board

All I have so far

you can read a lot of the components numbers here

Cheers, nice pics

And I vote for blue boards because that's what I've seen most. But the blue board has the "diode placing problem" for the Cinelabs/Omegaman HVT..

This problem is resolved by the way. Tracks moved over a little

If I only make 1 board, all problems will be resolved
