Re: Telequipment D34 Scope
Chris, I just know somebody had a D34 with corroded main board. I think it was BER.
I have come across boards with the little 1.2v memory cells, with serious corrosion damage. I have repaired them by by digging up corroded traces and replacing with insulated wires. Some times you need to dig out the board if it is a high impedance circuit. Others scrap them.
S22, D32 and D34.
S22 is a 5MHz single trace scope, 1.2KV acceleration voltage, so likely mono-accelerator.
D32, 10MHz, dual trace. 3Kv, so probably a pda tube.
D34, 15 MHz, dual trace, 9Kv, so clearly a pda type.
They are all mains, or internal 6 off rechargeable "D" cells
Les.
