ERRORS known in printed material

Hi All,
"Errors" in printed material are a real PIA, so I decided to start this subject, and point out all I can recall at the moment--please feel free to add anything you discover to it ( just click on "edit" and you should be able to add "stuff")--please, be 100% sure that you are correct, and do it by brand name--

My books:
-- "The Seeburg MicroLog Trouble Shooting Guide" contains too many to list here, and should have come with a one page "errata sheet". The last error was discovered on 9/08 and the sheet is dated such at the bottom of the last paragraph. If you need a copy, email me at: ronnnrich@yahoo.com
"The Seeburg MicroLog Digital Trouble Shooting Guide--2nd edition": No errors known --yet--
---Seeburg Mechanism Guide", several errors--errata sheet dated 11/08--once again, email me, if you need one.
"---Seeburg Mechanism Guide:, 2nd edition, ( 1st printing-- "Spiro bound") Page 51-AMS info wrong. should read 33/16 rpm, P-6*, N-8/O*. Page 55--N-9 should read 253793. Page 66, third paragraph, from bottom --states "--coil in the "U" models"--should read "-- the "V" models." Same paragraph states "--units used on these models." should be "---on newer models."
2nd printing--staple bound-- no errors --yet--
Tony Millers books:
--- "Seeburg SHP Amp. book", page 39, items g, and, h. Change the word "emitter" to collector, and the"E" to "C". Several places in the book, Tony refers to the "new bias circuit", and states it was done on the SHP-1 run--this is an error, as it was not done till the SHP-3, Code C run. As for the SHP-2, I don't know if/when it was done (Ron Rich).
Page 55--309687 is listed incorrectly as 309867--also replacement is listed as MAS A06--should read MPS A06
SEEBURG: All "45 TASU" schematics--If shown, the ground on the control pot should have been drawn on the case side, of the pot--not the "wiper" side ! NOT shown on most schematics--Jumper should be added from pot (case), to common wires, on relay points {usually black wires}.
Seeburg HSC-1 Service Manual--- In The CCC, Added 40 vdc connection to pin 13 on the mech jack. Also, 5 amp fuse added, in series, to that line. Page (2-2) 53, "2M4" contact adjustments. 1/64 gap in scan--closed in transfer/play ( NOTE: this is for code "A" mechs only). Code "B"mechs, Open 1/16th (.040) minimum, in scan--closed in play and transfer (holds RR while playing second side) Page (2-2) 72, left out of the early manuals--needed for "U" or "Code B"--all models, including the AP's.
Seeburg "6000" series Home Stereo's ---Supplement manual needed for both, early, and late versions--many schematic errors in early manual--
Seeburg SS-160 manual, mechanism schematic--fusing not shown
Seeburg USC-1 ( and maybe more ?) manuals--Clutch reset lever switch, 2M1 contacts--states "closed during transfer and scan--"-- NOPE, impossible ! Open during transfer---- set for 1/64 inch open in PLAY, do not attempt to keep it closed during transfer !
Seeburg USC-2 Service Manual-- DCC-2 & mech trip circuit is incorrect--see DCC-3 manual. See "160 electronic parts manual", issue 3, for changes/additions to the 311125 PCB
Seeburg --ALL 45rpm "Autospeed" schematics are wrong--the pot is wired so the ground is on the stationary portion, rather than as shown, on the mobile portion.
Seeburg SMC "Tech Manual"--Mech schematic incorrectly drawn. Shows 1M-4 as being closed in play--should show it as open in play--note 1M-4 must open a minimum of .010, JUST as 1M-6 just makes !

Regarding the SHP Amp Book....There is also an error in the numbering on the photo on page 42--The two chassis mounted caps
are numbered in reverse for the SHP-3--"outside" one is C-66.
(admin note): Use caution here, as some production runs used a metal anchor for the outboard cap, in which case, the numbering shown is correct. NOTE: Brown wire is neg voltage, in all cases.

Page 46, Tony mentioned a "SMC,Jr."--This MAY have been a "working name"( and does appear in other published info), but no phono, using this name was produced. The equalivent model, using the "MCU system") would be the "DaVinchi", and ID tagged "100-79M". RR

Jupiter 120C / E100 service manual - schematic power supply:
wrong: capacitor 2x 3µF/550V
correct: 2x 32 µF/550V

Rowe/AMi manuals that state either "no lubrication", or "5 year lubrication" are, IMHO, flat out wrong.
Motors, at least, on these models, need to have their "oil wicks" kept wet, with 20 wt ND oil---If you don't want to replace them--that is---Ron Rich

Tony Miller's SHP AMP Book Page 44 Preamp Board Diagram has duplicate capacitors shown. There are two C5111 and two C5128 shown. The top most C5111 (next to C5113) is actually C5114. The top most C5128 is correct. The smaller C5128 in the middle is actually C5108 a Tantulum 1uf 35v.

I have to add my two cents.... of course.

Regarding "errors" with Service Documents...
Please note they are assembled by humans - and humans as we all know, are prone to making mistakes.
That late-night beer-blast with the guys, or slightly irresponsable employee trying to get laid....

Additionally, mid-manufacture, some products also have component changes/substitutions not listed on the Service Info - thus the term I'm sure we've all seen:

"Specifications and Features subject to Change without notice"

I agree with Ron re the oiling of the motors.
The problem with telling anyone to oil anything is that they always go over the top, oiling will result in very clean mechanisms when cleaned up but they will need a lot of parts relacing because of the wear to the parts.

When people oil the gears on a R-84 to R-94 the oil drops onto the Sprag Wheel and rots the Stem Bushing and the oil builds up on the Magazine Gear and gives errors on the opto switch.

The first thing we do when we get a mechanism in is the remove all the lubrication and start again.
and lubricate only where needed and only slightly.

On the 1100 & 1200 mechanisms the gripper bow assembly should never be lubricated other than high melting point grease in the trunion casting pivot sockets. the nylon cam & trunion gear act as self lubrication against the cast gears. On these mechanisms one drop of oil on the idler wheel linkage at all the pivot points, oil the wicks/bottom oil tube on the turntable motor an put a film of oil on the turntable shaft using your finger, also oil the wicks on the transfer and mechanism motors.
IMHO that is the total lubrication on these mechanisms and the R-84 to R-94 need none.

Hi Alan, and all,
One thing always "puzzled me" about RoweAMi's oiling recommendations--some "instruction sheets" say to oil the
"nylon bearings" -- I asked a Rowe factory engineer about that one time, and he muttered something about "leaving sleeping dogs lie"-----Oh, BTW, one of those "instruction sheets" that I have, says to add oil to the grease used in the trunion casting---

Rowe R-83 amplifier (125 watt version) the preamplifier schematic has the pinout for chip Z1 not listing the pins 3 and 4 going to a capacitor. The printing makes it look like the pin 1 is going to a capacitor, but pin 1 is actually preamp section "A" output.

Ken,
In which "manual" ??
Ron Rich

It was the Field Service Manual and Parts catalog.
