I could use just the F4 and drop the voltage gain to zero ( lol ) I have no doubt this thing will drive it fine. My jet boz does. right now I set the pot at halfway point and use remote control on CD player. Your 6v6 pre and the F4 are a great match

2X DCG3 with just the F4 is perfect for my system. Can't wait for TKD to get here!

You have better hand on the pot and even better background details with this system gain structure I suppose?

I examined the 2CP-2511 TKD 20k model. It measures 18k across and has 4.5k Zo at the 1/2 signal division point. Derived from output signal level drop when applying known loads.

For all intents and purposes its nominal value should be chosen for replacing same nominal value series pots. Because a series has max Zo a quarter of its Zin.

A series would not max out anywhere else than at the 1/2 division point. The TKD Zo also shows 6.3k at 1/4 and 4k at 3/4 division. Its an own kind of pot. But the Zo range is compatible enough.

So if we have access to all the TKD pots, which one should we buy? Now thinking about changing my Alps blue pot.

If only the 10k TKD is available (and if you don't like the tonal balance with it) add 2.2k good quality resistor in series from wiper (pin 2) to the DCG3's input.
