Partial Update 8/18/2010 1700 hrs Z
There is a vast amount of information on the web concerning QRK idler drive turntables and it's rightful place in the radio industry history whether in "on-air" broadcast studios around the globe in production rooms, now as well in many collector's small studios. We have put together some interesting material from many outside sources and different web sites to help anyone who seeks knowledge of their QRK unit to find answers to most common questions in one place.
This site is fortunate to have somewhat of an inside look into the in-house memos concerning QRK, sales, trouble-shooting guides and general knowledge concerning QRK units as well as how the "higher-ups" compared other branded tables against their units. We are grateful to and want to thank Bob Martin aka "Fresno Bob" Martin for his expansive knowledge and continued help in compiling many facts concerning QRK and other audio components. A lot of information we are posting has come to us through the sharing of documents from "Fresno Bob" when working with QRK in the 1970's/80's as head of sales, then moving over to Broadcast Electronics in the early 1980's. Some of the documents are a bit "light" or (banners not legible) yet readable due to using a non-commercial scanner. If you notice slight font change on the documents, this is due to "fixing" where we add the right letters the scanner did not pick up. We will be able to copy this original material and post it as the original was typed as soon as we get the scanner up and running again. This material will be added to as time permits; also more HERE.
ATTENTION QRK MODEL 12C OWNERS: QRK used a slightly different combination of Plateform Shock Mounts. Depending on the production run, instead of a PL100-A (1/2 lb.) at the back of the motor hanger plate, the 12C uses a 100PL-1 (1 lb.), with 2 100PL-2 (2 lbs.) mounts on either side of the motor. We have these, and a set of 3 (Part # 3-SET-QRK) is priced at just $32.40 [plus shipping]. Also, due to production changes in the molding of the 12C base--as well as where the screw holes are placed--a "diamond-shaped" Plateform Shock Mount may be required, depending on the age of your table. We have a supply of these in stock; contact us at parts@russcoturntables.com to order a set today!

During one of Bob Martin's "QRK Seminars" and confirmed with more detailed conversations with him, I find that the Galaxy turntable is quite readily and easily converted to a 3~speed, (33/45/78 rpm) variable-speed control turntable.
It is most simply done by utilizing a three position single-pole rotary
switch with precision resistors in series with the variable speed pots to establish the three speeds.
Bob also mentioned another point, applicable to any variable-speed turn- table. This is the problem of the knob-adjusted speed control, which DJ's can "diddle" with. From a hurried examination of the unit, it appears to me that a universal mouI1t could be developed for the speed control permit-
ting either knob - or recessed screwdriver access - speed adjustment.
It seems to me that a 3-speed dc instant start version of the Galaxy would be quite marketable.

INTER OFFICE MEMORANDUM DATE October 29, 1980 TO C. Kring FROM L.J. Cervon R. Weaver cc: J.Engle R. Weirther C.Fosmark J. Sutcliffe T. Ash B. Martin Re: Model 12C Turntable I noted that the estimated actual cost of the 12C Turntable is running above the $214.45 standard cost. Even at standard cost of $214.45, our cost ratio on the $350.00 selling price, after the 25% distributor discount which is effective November 1, will be 81.7%. When we add to the cost the contingent fee to the prior QRK owners, the cost ratio on dealer sales increases to 86%. Comparable Turntable prices are as follows : Harris Model CB-1201 Two Speed, 60Hz $345.00 Harris Model CB-1201 Two Speed, 50Hz 355.00 Rusco Cue Master, 3 speed 355.00 Rusco Studio Pro, 2 Speed 399.00 Cetec Model GT 12/SY, Two Speed 375.00 Micro Trak Model 720, Three Speed 355.00 Micro Trak Model 740, Two Speed 399.00 I don't believe it is economically possible for us to maintain the $350.00 selling price on the 12C Turntable. As much as it is embarrasing as well as confusing to change prices soon after a price list is printed and mailed, I see no alternative but to suggest that we increase the 12C price to $375.00 effective December 1 on all orders. Also, it's very important that we be very strict on the new 25% discount and not allow anything greater for any order received after November 1. Please let me have your. comments regarding the suggested price increase on the QRK Model 12C.

INTER OFFICE MEMORANDUM DATE November 5, 1980
TO Curt Kring FROM Bob Martin
Ref: L. Cervon's memo dated October 29, regarding the suggest price increase November 1, 1980.
I really feel it's a bit premature to suggest an increase on the item at this time.
From the information that I could gather, the $214.45 standard cost figure isn't fully documented. It appears to be based on the QRK labor/hour standard set in- Fresno and then brought in, and applied against the current B.E. labor rate. We are still running into discrepancies in the QRK methods on a daily basis and haven't had enough experience with the product to get a complete production picture.
For example; the platter assembly was QRK costed at around $41.50 per unit. With the few changes we've already made, the BE standard costs hover around $24.00 a unit. There's about a 40% difference in the cost figures! Again, these labor/cost figures are based on standards set forth from Engineering and what little experience we've gained in 2 months of production. Another point: We're still planning to import the aluminum chassis, raw platters
and motor bases from California. The resulting freight costs won't influence the unit cost directly. But further down the line, these figures in the cost of goods sold (freight) will offset gross totals, and ultimately effect the profitability of the product.
As we gather experience on in-house assembly procedures and production know- how, ba~ed on typical learning curves, the decrease in labor hours will off- set the inevitable rise on material cost and labor rates. From the little changes we've seen in such a short time we might well expect an overall de- crease in standard costs!
The resulting confusion on price changes again, along with newly instituted QRK Dealership structures, elongated delivery schedules (already 45-60 days typically!) can only damage our marketing position. I suggest that we delay the decision of price increases for 30-45 days, and then examine the newly revised, in-house documented B.E. standard costs that will be available to us January 1. At that point we can make a more informed decision on the profitability of the 12C turntable.

Re: QRK/CCA Replacement Parts
During the many years of operation at the California plant site, there were many products introduced onto the broadcast market with the QRK or Rek-Q-Kut names' involved. Be it necessity, convenience or marketing related; it has led to much confusion as to the availability of replacement parts for products exhibiting the QRK logo. Subsequently! we must draw a responsibility line as to who can supply what for who to alleviate some of the congestion.
The attached guide is written up as an aid for us in helping the customer locate parts we can no longer supply or at least direct them in the right direction.

INTER OFFICE MEMORANDUM DATE December 5, 1980
TO R. Fannin/Shipping FROM B. Martin
It has come to my attention there is a potential problem in shipping regarding
some QRK turntable replacement parts.
Apparently, when QRK motor assemblies (#830-0016) are being shipped to customers, there is little effort being made to protect the assembly from packing material: if effect the white packing pellets are getting into the motor. There is also no provisions being made to protect the pheonolic capstans. These are sensitive fittings and a jar as little as a flick of the finger can knock these out of true. I've got 2 calls from customers who just received shipments with these motor parts protruding from the side of the box!
Suggest immediately that we use a card board tube of sorts taped or tied down over the capstan of the motor and individually wrap the motor assemblies in a plastic bag to protect it from packing material getting into it. Action is required immediately.
