Used_Siemens & Halske_E88CC_Double_Triode_Approximately Matched Pair -05.
The brand logo is worn.
After 50–55 years, this is not surprising.
Settings of the "digitised" instrument :
- Anode voltage : 90.00 Volt.
- Heating voltage : 6.30 Volt.
- Bias voltage : -1.30 Volt.
- Anode current : 15.00 mAmper (100 %).
- "S" : 12,5 mA / Volt.

TERMS :
Winning bidder pays
actual shipping cost.
The net weight of
the goods is: 24 grams.
The gross weight of the packaged goods is: ~ 45
grams.

Wenn Sie mehreren Artikeln winnen,
ziehen wir sie zusammen.
So können Sie an Lieferungkosten
sparen.
If you win several Items, we will
combine them for you.
Thus you can save on the shipment
cost.
