I did read somewhere else about the low gain of the Denon . I also don't really have the experience to start getting to clever with changes .

I'll look around for the Dynavector .I have a few contacts here for the that sort of thing .

I noticed my name on the list for the Salas reg . No rush . I might have it finished in time for the Christmas carols. I have an amp project that has taken
priority.

Rich,

The Takman and Holco should be on your list, especially the Holco, if they are the original with non-magnetic bodies and leads.

Here's the thing though, in a critical area, like the load resistor, you might want to try something more transparent, like a Charcroft Z-foil bulk resistors. (Other will disagree and feel it is not necessary.) We call them the Nake Vishay Z-foil resistors around here. They are expensive, but there is suppose to be nothing better. I have some for a simple preamp, but haven't had the chance to use them yet.

Cool thing is, once you settle on the value, you can swap them out to see if you get an improvement or not.

I've heard and read good things about Grado, the Blue Note No. 2 and Shure Shure M97xE 2 and Benz Micro. These brands all have reasonably priced carts. I use the Denon 103R. The difference between the 103 and 103r is the purity of the copper winding; the R is better. Mine is outfitted with a Soundsmith ruby stylis and Midas aluminum. However, I won't see the benefits of this cart until I build the Pearl II.

Have fun and good luck!

Vince

Cheers Vince ,

the Takman are half the price of the Dales ... Save some for the Charcrofts you fancy .
As I'm ordering for a balanced B1 and the Pearl 2 saving a little is always nice .

Nothing wrong with that; just so long as you know that the alternatives exist.

On one of my boards I'm seeing unstable voltage at R17. It drifts 2-300 mv after a short time. Should I replace P1?

Did you implement C7 ? Wayne stated that boards finally wouldn't need them, especially if you use ZVP3310 and Pearl II original layout ...
It would give some instability problems to some users if I recall.

I did implement C7. I'm using ZXP3310 in Q2, and I assume I'm using the original layout. I'll pull C7 tonight and see if it helps.

C7 is removed and voltages are stable now

I also implemented your ground scheme by grounding the outputs to the PS ground, isolated from the case, and grounding the case to earth.

Yes, it's a fine sounding unit.
