We have experienced some failures of meters on power
amplifiers which can be divided into 3 groups:
1. Lamp Failure- we have replacement lamps which
may be soldered in. Please do not discard the
meter. Some lamps have a plastic sleoeve whic h
discolors with age. We will replace these lamps
under warranty for customers who request it for
two years from date of purchase.
2. Pointer sticks- usually caused by number scale
being mispositioned. This may be easily remedied
using a scribe by carefully removing and repositioning
the scale. We also have meter scales in stock.
3. Meter movement burned out- Replace meter. Check
meter amplifier input caps. for leakage and replace
if any doubts.
