#1

I have a few DMM's and a real nice analog with a large dial from 1963,good impedance and V range settings starting from 1v full scale.Do I really need VTVM? They sure look nice and I have a real itch to get one, just would like to know from the practical point of view. Thanks.
#2

The only thing I ever use mine for is peaking alignment with the analog meter.
#3

So, won't my analog meter be sufficient enough for the alignment?
#4

I think any modern meter is sufficient for anything.

The old type low Ohm/volt meters are good if you want to read exactly what the techs read back in the days using their schematics, so if the diagram says "90V" this is what you should have. But you could always adjust for a modern High impedance meter.
#5

any analog meter with adjustable voltage range should be fine for alignment.
#6

Would a scope work instead of a vtvm for alignment?
#7

Yes but its easier for me to just clip 2 wires of the meter. A scope is more accurate but not so much as to be noticed.
#8

Ahh, good to know. My vtvm isnt working so I will use the scope.Thanks.
#9

like with a meter, you adjust to the highest freq peak.

Yeah, always wondered why they call them spirits "odorless". It sure enough smell like a gas station.morzh — 10:10 AM

No, it did not use photo-finish. It is veneer with the shading on the front of changing darkness.morzh — 07:52 AM
