Anyhow, here is what I think I would do if I use the Alnic’s Preamp. Get rich the 7721 and 7788 and to put in there my 6E6P-DR in triode mode. The tube has very same pins and a full equivalent.  Increase the plate voltage to 200V. The 6E6P-DR is 8W driver it is a very powerful driver with 33 times gain. I would driver it with 22mV that would make it ~ 5W. I n this mode the 6E6P would have 1K on pals and the ratio of the transformer need to be adjusted accordingly – it looks like Alnic doe good transformers as it will not be hard for them….

Anyhow, it looks like Alnic’s Preamp  is very versatile unit and you can put in there many tubes… Still, I would not use the 7788….

How would modifying preamp affect sonic character other than just providing more gain.  What's the advantage? Once such a modification is made are you restricted to using the 6E6P-DR tube only?  Will it change the sound of 7721 & 7728 tube?
