Altec A7/VOT Bass Enhancer?

[Earl K]

Lemme see, I know my ancient Fluke doesn't,
but I bought a cheap inductance meter recently for tuning coils.
Honestly haven't looked to see if it does caps -

You think the values are different than the marked values?
(Of course it HAS been 52+ years)

My interest is purely academic.

I don't really know if they'll be far off ( in value ) or not.

Current group-think is these caps are NP electrolytic ( which by inference would suggest the values should have drifted by a large margin ).

OTOH, my research ( & single example dissection ) shows the caps might not be electrolytic ( which happens to jive with all the measurements that I've made of this type of cap where the values I measured where unexpectedly close to the stated values ).
- Still, my own experience doesn't translate into not replacing these sort of caps, since there are indeed better sounding caps for the job at hand.

As I said, it's a purely academic interest.

And yes, apparently that new Meter DOES do caps! heh!

in 200ufd range,
One measures 116, the other measures 95.5
