If anyone is still watching this thread ---- Thanks again to MTF for ALL the help and especially recently. So here's the NEW thing ---- I got back into this unit to repair some other issues. Got to playing around with output transistors. Long story short - while waiting for parts delivery I...

Hey Markthefixer - great to hear from you again! "what leads you to this conclusion?" The case is cracked and the readout goes blank every once in awhile until I tap on the trimmer case just right. it seems to function when adjusting. maybe some cleaver super glue and redress the solder joints?

Hey folks looking for some info on the trimmer capacitor on the Indicator assembly. On schematics it is TC-1. All I can find on the component is AKM-010. I can't find anything searching on computer. It is broken and I need to replace. any is

I like it! looks like four Oscilliscopes -- or are they something else? I can almost make out a Kiethly. I have a 2015 and love it.

Not quite sure what you are refering to about Adjustment vs calibration. I guess that is why I used the term adjustment. I by no means would say I calibrate any equipment but I do go through the service manual and checl and "adjust" if necessary the various parameters. Especially if...

Thought I would pile on. I only have a small space here in Germany. would like to spread out the bench space when I get back to the states. Just about everything here is 'bay buys and repaired or adjusted to working condition. Except the R&S Oscope got it direct from factory in Germany. The...

SO I want to talk about the sound-- I have a redone Pioneer SX-3800 and Yamaha CR2040 -- they sound very good, defined, powerful, clear. They were the basis for comparision with this receiver (2265b) -- at first I thought it was the "Marantz sound" but with just a recap it was soft around the...

So This started as a minor repair (output transistors), re- cap, and replace diferential pair transistor but ... I wouldn't say I was unhappy with the sound I just thought it coulds and should perform better. So here is the transistor listings , I used -- please note I matched every transistor...

and back: The case I bought separately from a company here in Germany.

And the money shots -- finnished - for now

and after (still a couple remaing , see blue marks)

I'm just going to show the tuner board before and after (just re-capped but thay are a PITA- becuase so many and differing caps).

pre/tone board cleaned up: This board is also different from a regular 2265. It has some double transisors -- hard to see the larger cases in the photo. The have five pins and there is both a NPN and PNP styles. I matched KSC1845's for the NPN and KSA 992 for the PNP's. I match each set...

Pre/tone board (before)--- Yukkk -- cardboard below is so I can test during replacements without shorting or putting fully back together.

New output transistors replaced and mounted (the original problem)
