Hi Oliver. Looks to be of a darned good quality. Many thanks. Kevin
Hi Kevin,
Thanks!
I did go as far as the budget would allow for PCB construction and the guys in china have done a very tidy job.

New BOM!
I have found some discrepancies in the part numbers so i have double checked and updated the BOM.
Valve base recommendation now included.

I have 2 spare boards if anyone else is interested.
£30 + postage and i'll post anywhere in the world!
BOM and Build tips/pointers will be added to this thread in the very near future.
If you still have one left I would take it.
Cheers,
Heinz

Sure, I'll be in touch!

Hi Oliver. Pray tell what is the transformer's overall rating and the VA rating of the secondary windings? I am going to either have one custom wound, or see if I can get an R-core.
Mine is 40va
230v
SEC1 2X9V
SEC2 165V

Hmm, thanks. I'll have to have it custom made. Can't find that in South Africa. Where did you source yours, and I presume the voltages are "cast in stone;" the closest I can find is a 2x115V pri with a 250V sec (50mA) and 2x 7.5V (1A) sec.
Yes, custom and cast in stone I'm afraid.
I got mine from Toriody.pl
If you drop him a message he will give you a quote.
Airlink transformers will also make one of you ask them for a price.
I am sure there are others who will do it.
Alternatively, go for two separate TX's to provide the necessary supply. Not sure that would be cheaper!
It is! I have sent you a message.I will take the last one if it is still availble.
PM sent.
Speak soon!
Managed to get a bit more done but now I am out of parts!!
Really nice quality bits on the BOM but I have gone for Dale in the 27K 5W position.
I am also going to change the capacitor to a JB in the C131/231 position. The one in the BOM is possibly still too big for the allocated space. I will need to re-measure the space or try and find a better sized capacitor.
Some pics!
