Uncovered Guitar Effects & PA System Components ~ Need H

[Toppscore]

I have uncovered in storage a PA system my band used during the 1980s:

1) 1980 Tapco 6100RB (Reverb Board) rackmount six channel mixer
2) 1980 Tapco 6100EB (Extension Board) rackmount eight channel mixer
3) 1980 Tapco 2200 Graphic Equallizer with 10/EQs on two separate channels - rckmnt
4) 1980 Tapco CP120 Two Channel rackmount power amplifier

5) 1980 Ibanez AD202 Analog Delay - rackmount

==================
Guitar Effects & Footswitches:
6) Early 1990s Rocktron HUSHsuperC (rack-mount) guitar noise reducer
7) 1970s Boss DM-2 Delay
8 ) Two 1970s MXR Micro Amps
9) 1970s MXR Overdrive
10) Polyfusion SB-3 SHOK-BLOK (something to reduce static electric shock???)
11) 1970s DeArmond 1602 WahWha Volume Pedal
12) Original New InBox Jim Dunlop GCB-95 Dunlop Cry-Baby WahWah (no date)

==================
Real cool stuff. Most all has been in deep storage since 1983. All seem to work.

But, problems are with the first three (3) Tapco items. Both the mixer boards
with a total of 90 quantity potentiometer control knobs are all very hard/stiff
to turn/rotate. They all will move/rotate, but with great resistance.

And, the two channel ~ 10 EQs each channel ~ Tapco Graphic Equalizer
has stiffness or rough sliding on all 20 EQ up/down controls.

Anybody know why all 90 mixer board knob controls and
all 20 EQ controls would be stiff???

Anybody think they have a solution, like cleaning all the pots?

or can I take the knobs off and simply spray some WD-40 on them?

or are these three boards dead and not recoverable or worth repairing?

If the potentiometers need cleaning, is this an open-up
the frame/chassis kind of job for a tech pro? Is it worth it?


Thanks for any and all responses. Toppscore




***By the way, I have read that the Ibanez Analog Delay
is really an awesome classic vintage product. Thinking I'll rackmount it
and the Rocktron HushSuperC within a small SKB hard shell case.

I had one of those, or a similar model, Tapco mixer back in late 70s,
purchased new, and I remember the pots as being very high turning
resistance, right out of the box. Very stiff-certainly your setup didn't change during transport.

I wouldn't use WD40. It eats some materials/plastics.
Search Deoxit here - there was a thread about using it on pots.
Great stuff for scratchy pots & tarnish in general.

Don't use WD40.

Caig DeOxit is the stuff.

Peavey markets it under the name Funk Out™. It's exactly the same as DeOxit (Caig makes it and Peavey rebrands it).

Some Guitar Centers carry the Caig DeOxit line.

Sliders require "fader" lube which is also available from Caig. I use wd-40 for abosolutely nothing.

Some of those pedals you have might be worth checking into. You could almost buy yourself a small amp kit with the money you'd get from the DM-2 alone.

Yes. Cannot be a coincidence that all 90 knobs all are equally stiff.
Tapco was bought out by ElectroVoice.
Was started in 1969 by the famous Greg Mackie.
You'd think the analog reverb electronics would be worth something.

I'll try to sell all three on Craigslist.
They look near-mint externally with no corrosion or rust. Minimal scratches.
I just finished taking off eleven control knobs off an amp and
installed eleven new knobs, and that took some time (and patience).
Therefore, 90 knobs is not going to happen as I believe cleaning
the mixers properly, I'll have to get inside the case and spray the
90 rheostats directly. Bummer

Good to know. They are worth checking on.
A DM-2 sold for over $400 and mine is mint.
Wonder why the older effects are worth so much?

Got it. DeOxit is the one. Great internet reviews.
WD-40, not good on potentiometers.

Everybody is craving vintage. Some for the sound, and I think some just for the nostalgia. The DM-2 is completely an analog pedal with the old delay chip. Thats what makes it so valuable. I have an old Ampeg delay pedal that sounds quite nice. I like it better than my more modern digital delay. The funny thing is that the more desirable sound may be do the pre and post filtering and not so much the difference between analog and digital delay chips!

Your NOS wah-wah may also be worth something too. If you put your smaller pedals up on the auction site available to the international market, then you will get top dollar. For the most part it's not us North Americans that are paying the the big bucks for the pedals.

Thanks, Chappy. Yes.
Am going to take your advice and put them all up for EBay sale.
Not sure about international markets, as I'm not sure about shipping to
India, Africa, Indonesia, Antartica, North Pole or Nepal
Or some APO in Iraq

I listed ten other "long-stored" items on EBay.
Will see how they do. Toppscore
