Hei Mikko,
I believe they used a EAA91 diode valve in the probe for AC measurements. Andrew

Re: Grundig VTVM RV3 Type 6062
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
