yep...  no manuals!

in my opinion thats the hardest bit. No proper setup routine - make your own up.

compared to others I have seen this is a ball ache.

No proper schematic either - so it's a little harder to pin down when theres a problem.

BUT - you have the forum - and these guys are very helpful I'm sure.

Hi I'm new so go careful 

Just finished the Overtone HRM and have no output through the preamp. Power amp is working through return.

Voltages I have (UK) are as follows, some a little off and I can't see for looking where the problem might be.

ANY help is greatly appreciated...

Voltages:

Pin     1               2              3                 4                  5                 6                   7                8           

V1     200                          1.8                                 3.1                                      0
V2     212                          1.7                                 3.1                                      0
V3     297                           57                                 3.5                                     37

V5    0                             450                319            270                442                                  0


OT CT 455
HT 268 if I'm checking in the right places...

Any suggestions ?  the pin 8 of zero volts looks strange on v4 and V5 but the power amp does work. Pin 1 & 8 are tied so zero on both of those on V4 & 5....
I have some dirty pictures  : see below...

note the V4-5 was taken during the build but I think its ok - shows the build...
