hi, I'm looking for some trimmer pot replacements for my Marantz 2275 and 2230... (eg. 10-turn, 25-turn, etc. like those made by Bourns, etc.)
the originals drive me crazy, because the adjustment is so very touchy and very difficult to get dead on... the slightest bump, and the reading moves! (DC offset adjustment, etc.)
hoping for something that will drop right in and that I can still access for easy adjustments... also, looking for a good big supplier of these (hopefully in Canada)
I looked in my units and they are labelled:
2275
-------------------
R742: "202f6"
R7??: "202f6"
2230
-------------------
R760: "472-100K(ohm symbol)B"
R765: "472-470(ohm symbol)B"
thanks for any suggestions for the "best ones" to use!
the PHOTOS shows the backside of the 2 pots on the 2275, the white plastic parts (in the top-left corner), and also the 2 pots on the 2230 with adjustment screw (at top of amp module):
