Adcom GCD 600 CD changer has begun to skip when playing CD

Thanks for your suggestions. However I am using carefully boxed clean CDs and the skipping is on all. The Laser glass is clean. Since submitting the problem I removed case and the CD is lifted off tray by a lift motor which has a round nylon top on the shaft which "sandwiches" the CD against a freely rotating plastic piece in a lipped cylinder container. The lift motor then rotates the CD which is read by a separate fixed laser. My current suspicion is that the CD is slipping inside the rotating "sandwich". Hopefully someone who has worked on an Adcom GCD 600 can suggest a fix.

Adcom GCD-575: This unit has been the best

Back in the late 1980's the GCD-575 was about as good as you could get in CD players. Today it likely can still hold its own when rejuvenated to original operating condition when it left the factory (but can't play SACD's hires layer). Main problem... deteriorated main board soldering, a few hours with a solder sucker, (best to resolder use 2% or 4% silver solder everywhere) and replace 32 year old caps, and this set should equal the sound of a mega-buck player (also change the open/close belt). Modern caps are likely smaller so a 2,200 can be replaced by a 3,300 or 4,700 uF. part at the same voltage, etc. the output cap value should be doubled, and a bipolar used, or bypassed with a polypropylene or Teflon, IIRC plenty of room is available inside the case for either (or both). That is a lot of work. Well worth it. -Steven

How do i bridge an adcom gfa 5400

This amp is not designed to be bridged and can not be used in the mode you wish. Sorry, but internal circuit changes would be necesary for the amp to work as a single channel.

How do you connect wiring to bridge an adcom gfa

The manual does not specify a bridging option.

http://www.audioreview.com/cat/amplification/amplifiers/adcom/gfa-5300/prd_116265_1583crx.aspx

"Weaknesses:
Not bridgable."

Generally an amp that IS bridgeable uses the positive speaker terminals and some switching method to tell the unit to run as bridged. This is NOT a recommendation to try it on the 5300.

ADCOM GFA 5802 POWER AMP NO SOUND, BUT POWERS UP.

Remove the output transistors and measure each of the sets of 3 pads and report the voltage readings here. I suspect that you have either a blown driver circuit or output transistors. The voltage readings will give me an idea on where to start looking for specifics.

Thanks,
Dan

How do I eliminate buzz?

Things to check: 1. With your multi meter, measure from left ground to right ground. What do you get? Measure from each input ground to chassis. What do you get there. 2. Get or make a pair of shorting plugs. Plug those into the inputs. Power on. Hum there or gone? 3. Turn the pre-amp on. Connect. Level of hum change with preamp on? 4 additional information. How efficient are your speakers? This is a big amp, high-efficiency speakers may show some noise, while low-efficiency speakers won't. A trip back to the shop may be indicated, too.
