Advice on capacitors value on Quad 303 power amp and quad 22 with meridian 105.

I am new to this forum and have 2 questions seeking for advice.

1. I recently bought a quad 303 power amp.It has 3 units of assembled board. I found a small capacitor in the shape of a tiny piece of bamboo on the smallest board.This is the only capacitor ( i think) on this board.
Appreciate if someone can tell me what is the value this capacitor. How can i get a replacement.Can the modern cap be a good substitute .

2. I got the meridian 101 pre and the 105 power amplifier.I lost the 7 pins socket cable that links the 101 to the 105.
I am thinking of using my Quad 22 pre amp ( modified with external psu) to with drive the 105. Can this be a good match ?

Thank you appreciate for your advice and guidance.

Best regards,

Wong

1- A service man should go through all the electrolytic caps in the 303 and substitute where necessary. There is no diagram in https://www.hifiengine.com/hfe_downloads/index.php?quad/quad_33_303_serv... on https://www.hifiengine.com/manual_library/quad/303.shtml but it is indicated that the regulator board has no elcap. The diagram is here: https://www.hifiengine.com/hfe_downloads/index.php?quad/quad_303_service... . The small wires to the boards can break easily. I do not recommend to work on this amp if it is runnung fine and no competent repair workshop is available.

Dear Sir,

Thank you for your comment. Please refer to page 11 of the manual.It seems that there is an item C 200 ( C330MPI)which is a 330 pf capacitor. This item on my 303 regulator board is broken. can i replace it with a 330 pf mkp or ceramic capacitor ?

Appreciate your advice.
