*Note about parts sales

* Our "parts units" & parts are primarily archived for the purpose of restoration / repair of "Oak Tree Vintage" units first. Only if we do not have a "viable" unit in yet, either already in process or in line to be processed, that may potentially need parts from a "parts unit", will we release available parts for sale. As many of you know, the restoration of a unit can be a long, time consuming process. We may "lock up" parts that we may potentially need in the restoration of a unit. The parts are valued by the "potential value" of the unit they can be applicable to, time to extract, their rarity & condition to name a few criteria. A non-response to an email request for a part (we may have), likely means that we are still determining which parts we are going to need for the restoration or repair of a unit. Again, the parts are first for the restoration of our units and secondarily for the public market. Since we list the parts available for ourselves, it is not much effort to modify the menu's for web publication. Frankly, publishing them to the web, in many instances, makes it easier for us to determine if we have the part for our needs as well. The alternative would be to not offer them at all to the public, however most parts are always available to the public for sale. Thank you for your understanding.

NEW REPLACEMENT SWITCHES FOR
PIONEER
If the locking push switch on your
RG-2, RG-9, RG-60, SG-300, SG-540, SG-550, SG-9500, SG-9800, SR-9, SR-60, SR-303, 
and other
Pioneer EQ's, Reverbs, Dynamic Processors is not staying in, or will not lock, then here's the 
fix for you. May also fit other units. The original switches had / have almost a 100% failure
rate after a few years. If yours is not broken yet, it will fail and probably soon.

Failure is due
to a plastic locking mechanism that is many years beyond it's designed lifespan. The plastic part that fails,
is less than a mm thick, has a metal pin catching on it and is 25+ years old. Almost every time we bench
one of the above listed units, the original switch lock will fail after being depressed 1-6 times. Even if the lock functioned
when we purchased the unit we know it will either fail on us in restoration or on the buyer of the unit.


These switches will replace Tape Monitor, Attenuator, Processor 
and other push-in / locking switches on vintage Pioneer Gear. We have both 
12-Pin (4-pole, 6 pins per side) and 18-pin (6-pole, 9 pins per side) switches. 
They are a simple install for most electronic techs. Includes basic instructions. 
12-Pin (4-pole, 6 pins per side) -
$19.99 ea.

18-pin (6-pole, 9 pins per side) -
$23.99 ea.
Add  $6.50  Shipping to total 
VERY LIMITED QUANTITY LEFT AVAILABLE OF EACH
regardless of quantity of switches ordered.
If you have one of yours bad you should replace the other(s) now also.

WARNING: Electronic equipment carries dangerous and potentially lethal electrical currents. You should never open any electronic unit without proper knowledge of electronics and the hazards of electricity! 
Any repair / restoration should be undertaken ONLY by a QUALIFIED ELECTRONICS TECHNICIAN!

(4-pole Will also work for Sansui 7070, 8080, 9090 DB Audio Mute Switch)
