Hello all I don't suppose anyone has a good meter from one of these the specs are 100 ohm 0.5 Ma fsd.
Not sure why I want to repair this,mainly because I am board . It has developed other gremlins from sitting disused on a shelf for too long.
Kind regards Jimb.

I should also add if anyone is passionate about these valve testers I could be tempted to part with it.

Expensive but I have had a meter movement from an AVO 7X and VCT Valve & circuit tester repaired: Neither were damaged externally.

VCT fused the hair springs when it dropped screw & it shorted. AVO did the AVO thing & the balsam failed on the armature.

Both still in service.

Hi Marcc.
I have two other valve testers a Hickkok 530B and a Taylor 45c. So I guess I am not looking at spending much on this they were not a dynamic tester anyway. If someone would like it, and wanted to pay the freight which would be expensive because of its weight .
They can have it. It is a shame to leave it unrepaired either I get a meter or the the person with a good meter can have the tester for the freight costs only. I think it has developed other problems as well which is another reason I am not wanting a big spend.
Regards Jimb.

Ok I have found what I hope will be the other and only fault apart from the dodgy meter there was an o/c selium diode I have replaced it with a silicon one done the track I may have to add some series resistance to the circuit.At present there is no point because of the faulty meter.

Do note that if that has Paper caps in it same rules apply as in a radio but more so.

If that's for a car: wrong section. You need to actually find out who made it and what Model? Sometimes the factory work shop manual has it.

The vibrator itself may be common? The radio may be locally made by Astor or AWA under licence, or with GMH its possibly "Airchief" and if its imported, liable to be Firestone Tire & Rubber as that's their Trademark.

Buick would be GM-H would be Air Chief would be Astor.

What battery voltage, 6 or 12?

I have a vibrator car radio in the garage that may have a suitable transformer. I'll never do anything with it!

If interested, email me.
