Hi All,

I have my Stereomour assembled :), and most of the resistances check ok except for the last 2 >:(, # 47 and 48.
They're designated with a "*", -usually indicating fluctuating cap resistance.  These leads however are transformer taps.. Anyhow, these read as "open" on my amp. 
Seems like the surrounding wiring is ok, and as noted other voltages appear to check out. 

Any suggestions welcome/appreciated.

Thanks,

K.

Ah, no.  Will do.

Merci,

The "*" generally indicates that you won't see any kind of reliable, repeatable resistance measurement.  If you're not getting something close to 0 Ohms at these terminals, you don't need to worry too much about them.

Okay, reviewed that thread, and apparently Cowboy forged ahead with his voltage checks.
 
After checking all the connections associated with the a/c inlet and the trafo connections, seeing no anomalies, but still getting a steady, repeatable "0" ohms, I did the same.

Voltages  checked out, and amp fired up successfully. 

Thanks,

Kevin

PS: - Blackplate, do I interpret your comment correctly that the readings at 47 / 48 should be anything BUT 0 ohms, with normal readings fluctuating above 0 ohms, and steady "0" being an indicator of a short to the chassis or other issue?  -Really would like to figure this out if possible.  - Thanks

0 is a zero, or a dead short.  Open will show something like "OL" on your meter.

Ok, then, what I'm seeing is not 0.
The reading I have is "OL".

Thanks
