Proposed Mark III Layout

Tim,( setting the pots for the line voltage ) What that mean? Dale

Here are a few photos from the manual. It is the VR5 I circled in the schematic.

I apologize for the duplicates, I'll work on understanding inserting photos better. I included the second photo with the Vacuum Tube Audio...V11 to identify the instructions. The instructions are from several years ago, and as I recall came with the upgrade PCB. I've been working on this project seceral years.

It appears the current version of the VTA Mark lll PCB does not have the extra potentiometer, the "AC Balance pots", VR5 mentioned in the instructions. Perhaps I'll contact Mr. Motram.

That's the version I have. I started this project quite a while ago, the photos are from the instructions that came with the PCB kit from Mr. Motram. I suppose I should do these projects more quickly, but I really wasn't in a hurry. The PCB has the extra potentiometer.

I assume I should be concerned about the PS transformer temperature, it's just uncomforatble to touch for more than 30 seconds or so. Is it likely this is caused by using the SS rectifier? I think I read on one of the threads in this forum that the SS rectifiers may cause the amplifier to run a bit warm.

I started this thread March 3, 2015. I probably bought the Mark 3 PCB kit from Mr. Motram about that time. Perhaps he sold me old stock because I wanted only one kit, as I intended to do only 1 amplifier?
