How can I tell if this 68 drip egde black-line bandmaster has ab763 circuitry? It has the ab763 label but we know this is not always correct.

The AC568 revision was introduced on the production line in the second week of May. If your amp was assembled prior to the 19th week of 1968 it should be the AB763 circuit. The major visual changes between the two variants will be found in the configuration of the bias-supply adjustment and the presence of an anti-oscillation cap tied to the screen grid of each power tube (in the AC568).

Makes one wonder if these are legit original posts, or simply troll attempts. Some OPs are so desperate! Then, after several posts... no follow-up.

:lol:
