Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.
The manual is useful for trouble shooting for an old instrument. It saved money,and let me enjoy DIY.

P.SW: P.SW has extreme positive resistance-temperature characteristics. If an abnormal current flows to P.SW due to an excessive input or unusual signal, P.SW heats up and the resistance rapidly increases. With this function, the speakers are protected from excessive input or unusual signal. The resistance value increases even when using a soldering iron for repairing, so allow it to cool before using.
