Hello all of you wonderful Marantz gurus!
I've got a frustrating little issue to ask about.
Firstly, this was my first (mostly) complete recap adventure. I started with some swollen caps on the power supply board, then after more reading here went ahead and recapped the tone control board hoping to get rid of some of the brightness of this 2250b (it sounds just about perfect to my ears with the loudness on, but just a little bit harsh without it)
Those recaps went smoothly although the sound didn't change that I could appreciate.
Then for practice, I recapped the two amp boards. Again, went smoothly. These are sweet pieces to work on!
(Still no change in the sound which is good sound, just a little bright to me. Not as warm as other Marantz I have.)
However, I have this annoying issue with the tone selector switch (it was present before and after the recap)
Whenever is switch from off to on and back off, I get a soft "bump", it's a bit of a pop sound, kind of a "puh" sound from the speakers. (Not terribly loud, but noticeable)
And it's only on the first jog to on or off, not when switching to the other settings.
(Now, let it be known that I cleaned the ever living snot out of this switch!
I have deoxited it, I have used electrical contact cleaner, I have used nuclear strength electrical contact cleaner, I have use DeOxit Gold, DeOxit Fader Lube, DeOxit 100. I have prayed, I have cussed, I have q-tipped, I have sanded the disc thingee that slides between those swiper thingees. I have attempted my Jedi mind trick and am at the point of sacrificing a Tauntaun....!)
It's as clean as it will ever be....
Now what?
Is there a bad diode, capacitor, transistor, resistor, thermistor or any other -or that can be causing this? Does it need an exorcism?
I'm at my wits end...
Thanks in advance one and all!

Jedi mind trick. Now THAT is clean.
