Problem with Rachael
Yesterday at 21:09:52

Hi there...

I am trying to diagnose an issue with my system. I was playing music on my turntable this morning and later in the day put on another record. There was no sound. When I looked at my Rachael, the bias meters were both at 0. I have swapped out each and every tube on my Rachael and on the Aric (with the exception of the OD3 regulators). Both the Aric and Rachael turn on and the tubes are glowing. I also took the Aric out of the chain and the bias meters are still at 0.

Any ideas what the issue could be? Hoping it is something easy but feeling like it could be heading for servicing. Thanks.

Dick Posts: 25177	Re: Problem with Rachael Reply #5 - Yesterday at 22:03:31 Yes, generally the top fuse is the 5 amp for the rectifier full power, and the two other fuses are probably 250 ma (should hopefully be marked) and they are just in standard fuse holders and pop out. Usually, but not always, you can see they failed.

I have not had a Rachel or the earlier model since before Steve started putting those fuse panels underneath the chassis. . . (not on the bottom of the unit but if you unscrew the chassis from the base on the underside of the chassis where all the "wiring" is)--so I was unsure if there was one--if there is one, I think that may be a reason for the lack of sound.

If you have a spare main fuse in the holder in the IEC inlet try that. Fuses can exhibit weird behavior. As can rectifiers--if you have a spare one swap it in and see what happens.

If it was the fuses for the rectifier, does that mean that the tube I had in is bad? If I put that one back in, would it likely blow the fuse again?

Lon Seasoned Member "Love without guts is worthless!" Philip K. Dick Posts: 25177	Re: Problem with Rachael Reply #9 - Today at 13:02:16 it probably, possibly would. It would be best to have another rectifier on hand to use, and extra fuses if you want to try the original rectifier again.
