Hi Dominic
I said it would be the led.
I'm still happy for you to pop over.
I'll check everything else and i also have a set of
Audio Note resistors here if you want to fit them,they make quite a difference.
Look at position you fit led and check board marking not square or round hole mate.
Simple mistake....

The photo of five LEDs look the right way round according to the picture, but the two clear-red LEDs measure the 'wrong' way round - ill swap them and see what happens. BTW I added the two clear-red because the total Vf measurement was getting too high with 5 orange LEDs.

Thanks Steve,
I'd like to call round and have you 'cast your eye over' in any case. Ill get in touch when Ive had another try with the LEDs this weekend. I want to try with the Shinkoh and Riken before fitting Audionote resistors. Probably want to experiment with better caps too, obligato or Jantzen silver perhaps. Hope all went well with your dad.

Hi Dominic
Look forward to meeting you.

Spun the critters and it seems to have done the trick! Ive learned that I don't like resoldering one more board to go *X@!!
Some quick measurements on first board suggest its running at about 450mA and an extra 64Ohms in parallel is needed across one resistor to balance. Is this worth worrying about.
+ve -ve
Vout 9.61 9.57 V
Vdiff across resistor 1.216 1.167 Volts
R 2.7 2.7 Ohms
I 450 432 mA
Rbal req 2.59 Ohms
R2 req 64.3 Ohms
Still - chuffed to get it running - thanks for advice
