Re: RV75 Issues
Following up on my OP on this topic from Mar, 2023. I have finally gotten around to some basic troubleshooting on this otherwise pristine RV75 and have discovered a damaged resistor as shown in the

Re: Looking for L75 amp meter replacement.
Yep. No problem. It's the same meter (83T). That movement gets configured differently in the equipment. I'm guessing that your L75 has a shunt that is on the outside of the meter, since I believe the

Re: Looking for L75 amp meter replacement.
In my limited experience with taut band meter movements the band usually lets go at one end or the other. A dead giveaway (no pun intended) is that the pointer won't move when you give it a gentle

Re: Looking for L75 amp meter replacement.
The new one is not FS=200uA but FS=50MV. The scale is from 0 to 300 DC Amps. Have to check on that. Rob

Re: Looking for L75 amp meter replacement.

Re: Looking for L75 amp meter replacement.

Re: Looking for L75 amp meter replacement.
I wonder what it is that makes these meters so prone to failure? They certainly weren't cheap knockoffs. John K5MO

Re: Looking for L75 amp meter replacement.
That meter on eBay will work fine and fit perfectly. You will need to transplant the movement and shunt to your old meter housing, which is easy but requires care. The new small resistor should be the
