Re: AVO Model 9 Mk IV variation
Max,
Maybe we are narrowing it down already.
Not sure when the Mk IV was launched, but I'm guessing 1969.
It would appear at the moment then, the first Mk IV's had this Repair Unfriendly
design. Bit too early to make a definitive conclusion though.
We just need to hear from a few more Mk IV owners (Model 8 and 9's) to find the
cut-over Date.
Unfortunately for me, mine needs to be disassembled due to a faulty Rev MC switch.
Only get readings with the Rev MC switch depressed. Nothing in the normal position.
But it has to wait until my Model 8 is repaired, hence the removed Transformer Board
in my earlier Photos.
Still ,that's part of the Fun.
