Prasi,
1 is for V4H PeeCeeBee, the other is for FX-8 Bimo Mod & any other i might like to try it out on. BTW the FX-8 Bimo Mod is also from your Gerber files. Thanks again, the FX-8 is currently singing minus the Cap Bank.

Agreed...Alex mm is simply one of the best, if not the best Sprint layout masters around here!😉

Hi Prasi,

Is that some old AR loudspeaker behind the desk?

 

[Rick G]

Yes a pair of AR-3a's from 1972.

Prasi,
It is singing sweetly. The cap bank does help with all the music i have tried. it seems to me to help most with orchestral music that swells up. Gives it more body if that makes sense to you.🙂
Anyway, thanks again.

How about trying to avoid as many straps as possible? Especially those carrying more current...
