GD8 Germanium diode
I have one of these in a circuit, polyskop II, that appears open circuit on my DVM diode test. Is there any reason why this device should not test normally?
What would be a suitable replacement? Although the component list identifies it as "GD8 E" it is marked 8E R12 Don m5aky Last edited by vosperd; 5th May 2021 at 4:18 pm. |
