Quality scan, great manual. I solved my problem with this manual.
 ;
The AKAI 1720 model reel to reel tape recorder described in this Manual is quite an old unit - circa late 1960's. As a consequence, the description of the mechanical details - and adjustments thereof - is quite critical. The manual does this quite well. The schematics are also well presented and have detailed PCB overlays. Probably the only negative is that some half-tone detail has been lost from the original manual as it has been scanned in simple B&W.

Perfect source for service manuals: fast and professional transaction; high quality, perfect readable and largely scaleable PDF; complete schemes, diagrams and spare part list. Tnx a lot, cu again!!!!

I got your link from a friend and I must say that I am really satisfied with your service. Specially this B&O manual I didn't find anywhere on the web... but you could deliver it :-) . You deliver very fast and the copy is of good quality. So your webpage is bookmarked. Thanks

This was the Sony CCU-500A Service manual I was looking for.
The price was reasonable.
The permission to download was quck.
I will use Owner-Manual.com for all my manual needs.

LA7840 Vertical Deflection Output Circuit Features � Low power dissipation due to built-in pump-up circuit � Vertical output circuit � Thermal protection circuit built in � Excellent crossover characteristics � DC coupling possible General Description The LA7840 is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the sawtooth wave output from the BUS control system signal processing IC. Because the maximum deflection current is 1.8 Ap-p, the LA7840 is suited for small and medium screen sets.
TDA6108 Triple Video Output Amplifiers By integrating three video amplifiers in a single IC, the TDA6108 ICs provides a single IC solution for driving color TV CRTs. Each device in the TDA6108 family contains three video output amplifiers in one plastic DIL-bent-SIL 9-pin medium power (DBS9MPF) package (SOT111-1). Using high-voltage DMOS technology, this enables each of these ICs to drive the three cathodes of a color CRT directly, providing a significant reduction in the Bill of Materials for new designs. For maximum performance, the TDA610x amplifiers should be used with black-current control, enabling automatic black current stabilization and removing the need for any external alignments on the CRT board.
TDA8601 RGB/YUV and Fast Blanking Switch Features � YUV/RGB and fast blanking switch � 3-state output � Selectable clamp: � passive (with diodes) or active clamp � Bandwidth greater than 22MHz � Fully ESD protected � Latch-up free. General Description The device is intended for switching between two RGB or YUV video sources. The outputs can be set to a high-impedance state to enable parallel connection of several devices. A HIGH level on SEL (pin 5) selects the video inputs of Channel 2. The IOCNTR control pin (pin 16) defines the 3-state outputs and clamp inputs: � HIGH = 3-state outputs (also for test; active clamp) � LOW = passive clamp at the video inputs (diode) � Sandcastle: the video signal is clamped with an active clamp during the sync pulse.
