My Solartron 7081 has  a bad WR057 diode that needs to be replaced. It's 
a three terminal device that looks like two silicon diodes in parallel. 
It was making the meter read about 10.1V with a 10V input. Luckily it 
was temperature sensitive and was easy to find with freeze mist. Removal 
caused a shorted input to be about 2.5 microvolts high and a little 
noisy. I've not been able to find this device on the internet but 
thought that someone here might have seen this thing before.
