I have a Kenwood KA 7300 and sold the KA 701.
Kenwood makes very musical amps with beautiful midrange and big bass slam but a bit rolled off in treble.
You look like a DIY guy and with some tube fancies too......
Deoxit D5 comes with a solvent that provides flushing action, the D100 is better if there is a lot of oxidation to remove.For cleaning volume pots, switches etc:
Sir, can you please post a step by step method for cleaning vintage pots. Photos would also be welcome. Do you use fader grease after cleaning for lubrication and to prevent future oxidisation.Deoxit D5 comes with a solvent that provides flushing action, the D100 is better if there is a lot of oxidation to remove.
The products are costly but are really worth it.
I use Deoxit Gold to clean certain Vintage Amplifier's RCA jacks, they do the job pretty well.
Deoxit should be used on the Knobs/Swtiches, the potentimeters need to be removed from PCB and taken apart if possible to get the job done.
Do no spray deoxit all over the board.
Regarding the cleaning of PCB's with IPA is something i usually don't recommend.
Some PCB's the bottom of them is coated with a layer that prevents oxidation/rust from forming on the PCB over a period of time.
Using IPA will remove the protective coating.
The reason i tell to remove the potentiometer completely is because no amount of dexoit will help remove the dirt inside them completely .
And sometimes the dirt that loosens up will damage the resistive layer.
Attached are pictures of a vintage pot which i had worked on yesterday.
The vintage potentiometers are tough to find, and once damaged it will render them useless, tread carefully on these.
