Ah, yet another privileged one.

Their answers are as useful as your questions.

So, maybe formulate your question in a way someone might understand what exactly you're asking and add a little dose of respect? You might actually get what you want.

Well I think the question should be obviously !
So the response from the two "gentlemen",was not very helpful.
If they think C/65 is crap, that's ok by me :-)
Apparently these two are divine experts on this forum !!!

I did have a diagram, somewhere for that, but I am not sure if i cleared them out a long time back, when we stopped using them in the mid 90s. I may have kept them in a folder. I can have a look next time I'm working, but don't hold your breath. They did an OK job at the time and for us were reliable. Of course when we moved onto modern speakers they didn't have the power to drive.

Thanks :-)
Can you remember what the output impedance is ?

Posted by Steve Moore (Member # 4753) on 01-21-2018, 02:14 PM:

I'm afraid I don't, sorry. I know were were driving into a 8 ohm load with them but i don't know the output impedance. If i find any info or old diagrams i will let you know.

sorry but i was so happy the day i put all the cinnemecanica amps and paperwork in the bin they are a terrible unreliable amp switchs that get so noisy they pop the output drivers power transformers that the leads short to the case had several that cell bias switch shorted blowing up solar cells and anyone designing a output stage using a pair of 2N222's is daft
do yoursekf a favor scrap them

Dear Mikael,

I'm afraid that after a good look around, I am unable to locate the diagrams either. If they do ever turn up I will let you know.
From this thread, it appears that we were the only ones (we had them in two screens) that got by without problems from them. Possibly helped by the fact we never switched the switches off and they went off with the main breaker. Well they did the job in the day, stopped using them in 1993 and 2000 respectively in the two screens we had them.

Sorry I can't be more help.

Posted by Mikael Christensen (Member # 9089) on 01-29-2018, 12:35 PM:

Thats ok.
Thank you for your effort :-)

I am sure I have the circuit you are looking for in the Cinemaccanica Victoria 8 book.
I worked on C65 in lots of cinemas and we never had any problems with them. I even install one on my DP70's at home in 2004.
