Jose Master Volume question
From the looks of the schematic I got where does the master volume tap in at V1 100K or at V2?

looks to me like its v2a's 100k ( cathode follower )harddriver wrote:From the looks of the schematic I got where does the master volume tap in at V1 100K or at V2?

im thinking it looks like this.
anyone have a part number for the zener diodes used in this master?
EDITED

Right - with the difference, that the diode's stripes are facing away of each other, and only the one to ground is a zener. The upper diode is a regular 1N4007.rockstah wrote:im thinking it looks like this.
Moreover the tone stack is a 33K/500p

The fault almost always is sitting in front of the amp

and u r correct. the schem shows 33k/.00047 = 33k/470pf but I'm only doing the layout to show where the master is.
but how can u tell on the schem the diodes being used i wonder?
Mark told me "So after the cap that goes to the master you add back to back 20v zeners to ground."

Just kiddin'!
I didn't see it on 'this' schem of course, but I simply know, how to place diodes, to realize a 'clipper' in a signal path. This are just simple rules of physics.
