Re: SCA-35 - slow moving train

Thanks for the thoughts, Jim. I hadn't forgotten about your 22k-to-24kOhm resistor change. I've now updated the master schematic.

I'll play around with the selector switch to see if there's any joy there for getting any of the RC network on the amp boards before the switch (not in the path of the phono circuit).

Thanks for the guidance on the DC heaters. That's part of what I needed to sort out you saved me a load of work.

Going to try to finalize and order parts in the next couple of days. Still waiting on the new circuit boards.

Thanks so much.
