B&K Amp Modifications ??

Eight months later, ya never know when your old thread pops back up to the surface !!
I never heard of the PAC version of the ST-140 Bob, you might want to call B&K and talk to Jerry the tech man, nice guy, he'd probably be able to tell you more about it.
On a side note: My M-200's sound totally awsome !
They have a big tube sound and easefullness not associated with many solid state amps in addition to a huge soundstage and vice-grip bass.
I'm glad I sent them to John at Musical Concepts, his mods are everything they say and then some.

Has anyone heard of the PAC version of the st-140. I have one and one channel is dead.

Circle Stereo (circlestereo.com).
William Green. He's good. Very good.

Thankyou,.................. anyone else to consider ?

To get improved parts (Blackgate Caps etc)etc, ttry www.musicalconcepts.com. I have no personal experience with them but have heard good things about them. Let us know what you decide on and what the results are.

Good luck.

Actually, I have the latest (at that time) M-200's and was thinking about having some of the internals reworked (power supplies, caps, wiring etc.)

What mods are you looking to do ? As an owner of three ST-140's and an hour away from Buffalo (home of B&K) try them first.My three will be going back to be mono bloc'd for my front three ch.And rebiased to match.Which means I get to buy two more.....
