Transistor ID.

[wombweller]

Hi if anyone can

I'm wondering if anyone can Id. me a transistor type as I'm looking for information on these.

The case is TO-3?
written on it is
OC36 G7614

The photo is not a good one but hope it helps.

This transistor belongs to a bank of transistor that drive clock distribution board.I'm looking at getting this running but I want to id the components so's to understand the circuit.

thanks in advance

It's just OC36 Germanium power transistor on TO-3! Little data is available on datasheet. Search on google.

What a beautiful piece of equipment. Really a very worthwhile restoration project.
The images are not very good, but the labels appear like they are written in Russian...

Hi Cheers for the data on that!! I will read through.

Hi schmitt

Your right it is a beautiful piece of equipment quite rare being x 12 1 sec Alternating slaves, much quieter than the normal DC. slaves with a clonk each second.

I have to find out what the transistors are doing within the circuit to help understand whats going on.The main goal is finding the voltage required to run the system.

I can't wait to see it running myself but one step at a time!!!

I will take some better photos as there's no Russian on the labels they refer to rooms within the BBC.

Cheers!!

Distribution board input.

Hi

Please see better photos of the Distribution board.

Any idea why so many Transistors? there are 12 slaves but 25 transistors.

How can I work out the operating voltage?

Cheers

I would assume the "Alternating slaves" requires a bipolar pulse so you need 2 transistors in push pull configuration. With only 2 transistors per slave clock coil, that's 24 per slave, though I don't know why you just couldn't drive multiple slaves with a single pair of transistors. Unless those are syncros.

Hi Kchiste

Interesting thought!! so if I had a constant 1 sec pulse (high) the bipolar transistor circuit would alternate that then?

Could you show me an example of a bipolar transistor circuit please?

Cheers!!

The two people to talk to on here are RODALCO and oliverb.
They both have experience with master/slave clocks.
The type of drive method would depend on the coil. How many leads per coil? 2 or 3?
There are various methods of making a classB push-pull amplifier. Here's one example:

Hi
No probs pal!! I have experience in slaves and masters but this is not the norm.Usually With Alternating polarity slaves we use changeover relays so transistors just threw me!!

My master gives out a positive pulse every 2 seconds but with the relay attached it gives (1 sec +) and (1 sec -) which drives the type of slave s shown in the board.

Cheers I will dig deeper.
