Shamrock 2 Posted December 28, 2015 Author Posted December 28, 2015 Kia ora Shamrock! Nice to have you on board the Carver train. Kia ora bro!
Shamrock 2 Posted December 28, 2015 Author Posted December 28, 2015 Im also into my sansui and have a couple of nice old AU series amps Sansui (AU-D11), Carver(...) . A man after my heart! Welcome. I have an Au d11ii it's awesome! Cheers 1
Shamrock 2 Posted December 29, 2015 Author Posted December 29, 2015 I removed the amp board from my Av806x that was popping and playing up . After reflowing any solder joints that looked remotely suspicious and reassembling.. Popping noises are gone!! Yippee While I was in there I noticed the transformers have jumpers for 240v (the unit is 120 volt supply, I'm running it on 240v with a stepdown) if anyone knows whether it's just a matter of Changing the jumpers or if there is more to it than that , would be a big help? The preamp may not be so easy to find the problem.. Might be time to make a dedicated thread for it.

I believe the fuse value must be halved as well. What model preamp? 1

I believe the fuse value must be halved as well. What model preamp? Cool! thanks thats good to know about the fuse ratings. No need to change the capacitor across the switch also? it does appear to be all there is on the primary side of the transformers. Im borrowing a buzzy little stepdown for the moment so changing the transformers setup to 240 will be great. The preamp is a CT28v , I have been unable to come up with a service manual for this one
Shamrock 2 Posted December 29, 2015 Author Posted December 29, 2015 Kve would that be all fuses in the amp or just the main fuse that need to be halved in rating?
zumbini 6,153 Posted December 29, 2015 Posted December 29, 2015 Congrats on fixing your 806! ....While I was in there I noticed the transformers have jumpers for 240v (the unit is 120 volt supply, I'm running it on 240v with a stepdown) if anyone knows whether it's just a matter of Changing the jumpers or if there is more to it than that , would be a big help? The service manual is in the CS! library shell. Here's an excerpt that lists the jumper locations: 1
B-Man 4,784 Posted December 29, 2015 Posted December 29, 2015 Kve would that be all fuses in the amp or just the main fuse that need to be halved in rating? Should be only the fuse for the main power supply. 1
Shamrock 2 Posted December 30, 2015 Author Posted December 30, 2015 I changed out the main fuse from a 12 amp to a 6 amp one, and redid the transformer jumpers for 230 volts . It worked a treat. It seems to sound better than when I was using it on 120 with the huckery little stepdown transformer I had borrowed Thanks for the input guys. Now if I could just find a service manual so I can check the idle current settings 1

You are now directly connected to your mains with more available current.
zumbini 6,153 Posted December 30, 2015 Posted December 30, 2015 ....Now if I could just find a service manual so I can check the idle current settings As I noted earlier, the AV-806x service manual is available in the CS! library. Click on the hyperlink and scroll down past Phase Linear to the Carver section. 1

I posted a request to change the title to "schematics and parts list". 1
