amp 41710-A

Hi all
need to pick your brains again,in the rockola 41710-A amp there is a component (cap) across the input socket terminals, there is no value marked on it only these numbers,1346531//35386 ,as one of the leads has broken off i need to replace it ,can anyone tell me what to replace it with, it is not shown on the amp schematic , it has 3 connections the two outer across the input socket (L++R) the middle to chassis
any help please

Hi Mick

Per channel is a 220 k resistor with a .001 MFD capacitor in series with a 1 M resistor parallel.

Hi Erwin

thanks, does this mean all the 3 components you mention are coimbined in the one unit as there is just the one piece in-situ in the amp, which of the connections in your reply is grounded as the one in the amp has a ground, could you make a sketch of the connections please,

cheers

Hi Bopper,

there are six parts combined in one module. In my schematic the P.E.C. 35386 is shown with 680k instead of 1M.

Hi Jens
thanks for that info and drawing i now understand and can now see it in my schematic, how do they incorporate 6 parts in a small module ? , again a big thanks for sorting out my problem, one thing do you know what is the wattage of resistors is a 1/4 watt ok so i can order the bits

cheers

regards

Hello Mick,
there is almost no power dissipated in those resistors, so 1/4W types are ok.
You can try to fix the PEC by grinding off the ceramic around the broken pin and solder a new wire to it.

HI Jurgen
hope your keeping well, i will have a try at your suggestion otherwise i will install one using the drawing and components,thanks for the help, just remembered, my last posting which you helped me with about my other amp ,i had a guy go over it and he just replaced the rectifier and now it's fine so thanks again

cheers
