I did not have the manual for a Whirl Pool gas dryer, therefore I purchased it from Owner-manuals. This is exactly what I needed. Thank you for the service.

I was so pleased to get the owner`s manuel within one hour! Thanks again.

Finding the owners manual for my Pioneer CRWM62R is greatly appreciated. I had searched several other web sites with no success. Although my manual was not listed on your site for immediate download, I recevied an email within a few hours that my ower's manual was posted for me. I had no difficulty downloading the manual for my 20 year old multi-cassette player. Owner Manuals provides a service that is valuable, easy-to-use, accurate , efficient, and priced fairly. I thank you.

Excellent manual - just what I needed. Although currently available only in German, their are lots of pictures which makes it all very clear.

PHILIPS PE1642 Owner's Manual
Hi,
you have complet fullfilled my expectance.
Price is OK.

The greatest duty cycle for the stop thyratron, V l b , occurs at m a x i m u m pulse rate and minimum pulse length. A t that time it is conducting for the longest period of time. Under these conditions the stop thyratren
w i l l be most subject to jitter and slowness.
ultivibrator tubes V l O l and V105 a r e particularly subject to microphonica. When changing V l O l and V105, it may be necessary to try several n e w tubes to obtain one which is not microphonic and which gives the required advance and delay. A small jump i the n trailing edge only would indicate that VlO8 is microphonic. .
-- Microphonic s usually appear as a small jump in pulse
A quick operational check for L2AU7 tubes can be made by exchanging with a 12AU7 not in a critical circuit, any position other than V l O l or
V105.
Interference Through Power Line Interference through the p o w e r line can occur when instruments on the line are not filtered or i f transformers connecting to the line do not have shields between the p r i m a r y and s e c ondary windings. The interference may appear i various forms. A n visual indication m a y be seen when viewing very low amplitude pulses on a very high sensitivity oscilloscope. The interference will cause ~ i n g i n g the leading and trailing edges of the pulse. at
Zn some models of the 212A Pulse Generator the filament transformer w a s constructed without an internal shield, Some of these models contained a line filter which is not shown in the schematic diagrams. If an instrument is known to cause interference through the power line, the line filter circuit s h o w n at the rear of the manual should be added.

ADJUSTMENTS
Pulse Length Calibration The PULSE LENGTH dial is hand calibrate d to the potentiometer in the pulse length multivibrator circuit. Composition potentiometers vary greatly in taper and can change taper after use. The calibration of the P U L S E LENGTH dial will be onlyapproxim a t e l y correct a l t e r the potentiometer has been replaced or has aged. An external time standard is necessary where high accuracy is required.
Following replacement of a component within the circuits V108 the calibration of the P U Z S E LENGTH dial should be checked, I necesf sary, the dial calibration m a y be adjusted for greater accuracy as fallows:
--
1.
2.
With pulse generator connected to a calibrated oscilloscope, s e t the PULSE LENGTH dial to 1Q.
If necessary, adjust C128 to obtain a pulse length of exactly 10
microseconds.
