Mikko from Finland hi. What kind of meter test probe that meter use?

Hei Mikko,

I believe they used a EAA91 diode valve in the probe for AC measurements.

for DCV: 1M Ohms in series.
for ohms: cables
for ACV: Probe with a rectifier tube E91AA ( to test <30V~ ! ) rebuild it.

the both tubes are E80F , can be replaced by EF86
the E91AA is a EAA91, 6AL5, EB91
