Funk's Bias board

[gar13]

Just got some board's from Funk in the mail the other day. I've got everything figured out except the bias circuit. It has 2 caps, where all the schematics I've seen only have one. On the build pictures I looked at I also could not see the bottom left hand corner of the board, nor the the underboard wiring. Is there a second resistor there? There seems to be space for one.

So I believe these are my options:

1) 1.2k -> 1n4007 -> 47uf/100v -> 47uf/100v -> resistor?? -> bias pot

2) 1.2k -> 1n4007 -> 47uf/100v -> resistor (15k)? -> 47uf/100v -bias pot

Any help would be greatly appreciated

Thanx,
Dave

This schematic shows the appropriate bias circuit for Funk's board set.

There's only the one resistor mounted on the board. But there's a second in the circuit which is soldered point to point off the bias pot.

Here's a photo of one of mine which is pretty clear:

Thanks, I hadn't seen the schem before.

There is also some good stuff here:

Perfect, I searched for a while, but never found that post. Thanx!
