Hi Jurgen
Yes you are correct I am not an expert but always learning.
Maybe I did not explain my method clearly. I am powering up with the valves removed with a low power input to check that the wiring is ok with no shorts to ground and checking for voltage presence at points in the circuit. I am not looking for correct v at this point. So sorry I should not have said checking HT ! Of course

Hi Hildegard
Thank you. I have removed the resistors in the pick up arm.
The extra resistors in the write in unit do not look like they have been added. The credit, write in and all the mech is working fine so I think they are ok. I did find a video on You Tube of the same jukebox and there was a close up inside that showed the same resistors in place.
Interesting to see from your link h

Thank you for the information. I did think that there would have been small modifications through the years that are undocumented.
You are correct it is 270k. I found a circuit diagram for a 41056-A (Rock Ola 434 ) which is a similar amplifier to mine and it shows the 270k resistor in the power circuit after the rectifier. It also shows a 2k2 resistor and 0.1mfd cap before the rectifi

Hello to all
My name is David and this is my first post here. I am working with a Rock Ola 1494.
First thank you to Stamann for parts and help.
I have all the mech cleaned and working and now am looking at the amplifier type 36196 - A
I am in the UK and I think the jukebox is a Nova import. It has the 220/240v transformer and had a Elac KST 103 cartridge which I have changed for a Pf
