Thanks for your suggestion Tweetldee but I could not find the STK8050 on
Audio Lab webpage. Again, if somebody could e-mail me some information on this chip I would be really grateful for the help. Thanks Ettore "Tweetldee" ha scritto nel messaggio ...

Yes, at least as far as I know. It should be a 50 W output stage with 16
pins on the IC. If you have any more info please help. BTW, if somebody is interested in the ampli diagram I can send it. Ettore "Tom Wright" ha scritto nel messaggio ... did Sanyo make the STK8050?

STK8040 ought to sub for that. I think they are both NLA, but if you still
need one go to my parts board and make an entry : New Message Board for Parts Requests and Support : WWW.TECHNOTRONIC-DIMENSIONS.COM/phpbb2 "JR3611" wrote in message hlink.net...

STK8050
Just got one of these amps in a few days ago - shorted output module STK
8050 - I looked everywhere & couldn't find a single one. My customer is picking up his amp (we'll see) which I told him is not repairable or not worth repairing at this point. Maybe he would like to sell it to you for the part - it does have one good 8050 output module in it. Reply to me if you are interested and I'll give him your email. -- (615) 591-7556 10am - 6pm Mon thru Fri please see our website: www.amprepair.com "er" wrote in message om...

STK8050
Hallo Todd,
Actually I was able to find a spare one here in Italy but I am still looking for a fault which seems to be present on the right channel of the ampli. That's the reason why I am now searching for a data sheet or at least a description of the STK8050 to be able to better search for the fault. Do you have anything on the STK8050 to help my investigations? Can you anyway ask your customer about at which price he may will to sell his ampli, just to have an idea if it would be worth to ship it here? Thanks. Ettore ha scritto nel messaggio ...
