Man I LOVE my PM670 :-*
dagoose said:I had some extra tubes in (thanks radiance!) and so i have some even better matched pairs now and that made a subtle difference. I used 6n5p's and out of 12 tubes i have some really nice matched pairs but i could do with just 8 tubes.
I only decided to just one 5687 in the sidechain anyway because i can't hear any difference and it's just more 'stable' and produces less heat and power. Even still with just 1x 5687 it uses a massive 104 watt! 8)
I also played a bit with the bias to even out left/right a bit more which also helped. I don't think that the -2.4v is an absolute.
The only thing i still want to do is put in better input trafo's, i know it will make quite a big difference. I did use edcors in my d-aoc in the beginning and upgraded to lundahls which made a BIG difference. The edcors just sound a bit muddy to me compared to lundhals.
I really love my PM right now and i'm glad i modified it!

With the ITT 6BC8 and the 6n5p i also have a little more headroom !
So i use the 6BC8 from ITT and it sounds great !!

Did you match your tubes?
tekno808 said:No, i don't have the need to match from what i hear and everything work like it should be !
But in a day or 2 i have a Digital tube tester with a curve tracer ( because I'm curious ), then i wil match and let you now if there is a big difference in sound ! But I doubt it .
All tubes i have are brand new (real NOS) and don't think there wil be a big difference !
