Tubes with different gain for Moscode 401HR

I am vertically bi-amping 2 Moscode 401 HR amps and would like tubes with lower gain for the HF than those used in the LF. Any Moscode users'/pundits' experience/advice would be most welcome.

I am currently using 6922s (6DJ8 - Amperex orange logo) for LFs and stock 6GUYs (+ 12AU7s next to them, so insides are 12s and outsides 6)for HFs and the sound is better than matching the 6922s for HF & LF.

You are not bi-amping, are you, Tvad?

The solution may well be a Differential pre-amp, such as the Supratek Cabernet Dual, with different outputs and tubes to LF and HF. Yet more $$.........

Problem with the 12AU7 on the outside means you cant use the higher gain 6DJ8 tube with it, so there is no way of getting differential gain.

May I ask what amp you are now using, Tvad?
