[sdiy] FS: Unique Odds + Ends

[BrightBoy]

I've been doing some cleaning in the workshop and have the
following items available for sale:

(1) Cherry 10x30 Matrix/Crossbar/Crosspoint Switch

This was made by the same company as the ARP 2500 matrix
switches and is in excellent used condition.

PRICE = $77 USD + $10 USPS Priority Mail Shipping

(2) Cherry 20x30 Matrix/Crossbar/Crosspoint Switch

This was made by the same company as the ARP 2500 matrix
switches and is in excellent used condition.  

It should be noted that the trace for Row #7 (only) was cut in 
two places by the previous owner.  The two wires that terminate 
at the terminal block on the back (see picture below) are 
soldered to each side of one cut.  Jumpering the two wires 
together will restore that break.  The other cut will require 
a tiny jumper be soldered in place.  All other rows are fully 
intact.

(3) 300 WATT 100VAC/120VAC STEP-UP/DOWN transformer.

Perfect for properly powering Japanese sourced synths
that have found their way to the USA.  A recessed switch 
on the bottom of the unit selects the input source voltage 
(100VAC = Step-Up) / (120 VAC = Step-Down)

NOTE: It is BAD practice to power 100VAC synths with 120VAC.  
You will put undue stress on the power supply and possibly 
cause blown electrolytic capacitors (that have aged to their
native, lower voltage)

PRICE = $21 USD + $10 USPS Priority Mail Shipping

(4) MUSICAL APPLICATIONS of MICROPROCESSORS by HAL CHAMBERLIN

New, mint, unread, new-old-stock 2nd edition copy with dust jacket.

This is the holy grail bible for any serious synthesizer builder.

PRICE = $50 USD + $10 USPS Priority Mail Shipping

SPECIAL DEAL: If you buy both matrix switches together, I will
throw in free USPS Priority Mail Shipping (Within USA only)

Payment = PAYPAL or US POSTAL MONEY ORDER

International buyers to pay actual shipping on any/all items.

Email with any questions.

Cheers,

Jeff
