I have another problem on this 494 I       just finished up. The sound is very tinny. like it's out of phase or       something. Like very high distorted treble. I tried different speakers with no       change. Replaced the needle        with a new good Shure. What are your thoughts on the cartridge being bad? It's       wired correctly. If that's not the problem then the amp is going to need       re-built. Your thoughts? Thanks!       > > >        > > > It could well be out of phase, the cartridge in these should be wired       out of phase like AMIs - when you say the cartridge is wired correctly, is       that as per diagram?       > >        > > I have an AMI as well and the cartridge is wired out of phase. On this       Rock-Ola it's not wired out of phase as per the manual instructions. The amp       needed re-built. It's all back together and sounds good now. Not as good as my       AMI but as good as a        Rock-Ola.       >        > OK, the previous models (490 series) the cartridge is wired out of phase and       the 12 inch loudspeakers sum the two output channels as per AMI. It's the       same amp (54510-A) that's used, strange that Rock-Ola should change back. I       must confess I don't        have a 494 manual though.              This box came with all the papers. Even the inspectors check list before it       left the factory. When I was having sound problems I compared it to my AMI and       thought I'd found the problem. Then I looked in the manual to double check and       saw it was wired        correctly not like the AMI. After the amp re-build it sounds good but my AMI       sounds so much better.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
