I am restoring a transmare 38.

The set uses a voltage regulator tube. It was not present. From information I collected, it is a 150 Volts gas regulator.

For the time being it was replaced by an OA2.

I will apretiate information on this regulator (Number and specs.) and the possibility to find one of them.

Also very interested to interchange opinions on this model.

I finished the chassis. It is working fine in all functions.The case has been restored too.
The following list is of items needed to complete the restoration:
1. Rear view to reproduce the rear cover which is missing.
2. View of the speaker switch wich is broken, to reproduce the original shape.
3. The knob that controls the function of preselected radio stations. Missing
4. The regulating valve. Is a 150 Volts bayonet socket. (similar in specifications to the OA2)

Any help will be apretiated.
