what is a good one?

I've had good luck with Gold Lion and TAD 5AR4 tubes for modern production.

That's exactly why I mentioned the slow rise capacitor multiplier.

I designed mine to show a rise-time of 30s, to match the 6CJ3 dampers I was using up until then.

The multiplier needed a 10uF 500V film capacitor to get there, with a source resistance of 3M approximately.

It has been working perfectly for many years, and sounds quite like the damper solution.

The bulk capacitors are two 820uF 550V Kemet ALC, which provides an edge for low frequencies.

Could you share your capacit5or multiplier schematic and how to set the delay, TIA?
