Default Re: AVO Model 7 Restoration

Unusual for the P adjuster to have broken there, a smear of 3 in 1 on the replacement one where bakelite meets bakelite won't do any harm. Occasionally you get a meter of this vintage where the orifice is moulded/drilled on the skew which puts extra stress on 'P'. If the bakelite has swollen/distorted later on this can exert even more force and 'P' can seize up. Don't expect a donor 'P' knob to necessarily fit properly first time..

'Q' and 'R' don't seem to suffer from this- but can have issues of their own.
