Hi,

I have a question about the soldering joints of the 500K-A volume pot. When I was finished Chris came by to have a look-over and noticed an error I made in the wiring, and since we were finishing up (late) on Sunday night I decided to fix it at home. Now that I look at the diagram again, I just want to make sure I'm connecting to the right terminals.

The shielded coax cable (coming from the lower terminal of the strip next to the 12AX7 socket) going to the 500K push/pull volume pot: my first impression was that the coax cable was connected to terminal 2 of the volume pot and the shielded cable (obviously) connected to the middle-left terminal in the diagram (terminology fail ).

Anyways, looking closer...it looks like both the coax and the shielded cable go across terminal 1 as well. Is that correct? should I be connecting them there as well?

Thanks in advance!

The shield of a coax always goes to ground so it goes to pin 1 of the pot as does the little wire from the switch part of the pot.

The coax conductor (center) goes from the wiper of the volume pot to R6 / 330K on V1. (see schematic and it will be clear) , so it only goes to pin 2.

Hmm - looks like I read that one wrong! Thanks for clarifiying.

I had the center cf the coax going to pin 1 and 2 because it looks like that on the drawing. In hindsight I should have realized that that would have shorted the coax .
