Re: Re: Re: Cheapskates

Ah, but it also looks like it could be based on the Elektra E624
Next time I'm at the reference library I'll look for some reviews.

Here you go guys, that earthed copper box does`nt house the d/a convertor as i thought, but it`s some sort of interstage transformer it has 3pin input and 3 pin output potted. The shielded cable comes from the small re-clocking /line condioning board to the input of that interstage transformer, the output of the interstage goes the the tubes. I finaly found the d/a chips, they were well hidden under the main board, and the numbers on them are YDG-101f and the other is GDR-101.
Can anyone shed anymore light on this, essecially the interstage trannie?
Cheers George

After some closer examination i`ve found that after the d/a convertors there are 2x op27 ic`s before the interstage trannies, (a buffer of some sort?), no one has replied yet about the use of the interstage trannie, is this some sort of Musical Fidelity idea, or is it common with the use of tubes in cd players.
Cheers George

Hi,

I had a look at the pics. They sure look like ECC88s to me.

Here's what you can do to make absolutely sure:

Check the valve stem (were the pin base is welded to the bulb) for acid marking.
If the tube is made in Europe, the base should have such a marking: usually two lines of three to four characters and figures combined.

Cheers,

My Technician MR: Peter Gay Suspects That They are ECC88 on The TUBE C D Player, and he has been Working on Tube Amps for over 50 Years, I guess he Might be Right,

I have one of these but the drawer is stuck and inoperable. Plays OK but cannot load cd's.

You could measure the voltage applied to the motor when the drawer is operated. Then you could derive if it's a) the motor b) the snare c) the electronics. Please post in the appropriate forum.
