Aaron,

The silver band, cathode, goes to ground.  Otherwise you end up with a reverse biased diode and no current will pass.

Thank you sir! I'll have this mod along with the PS choke finished shortly.

All right, guess I am going to have to bite and put a choke in the Eros.  I put the triad choke in my Paramounts and liked the difference.

Hello Xavier,

There are power supply dropping resistors in the Repro, but we have found with the quality of the shunt regulated power supply, the impact of using chokes in these positions is quite minimal.

As an experiment, you can remove the leads from the choke in your Eros and put the resistor back, the observe the changes.

Upgrading from the Repro involves a form factor change, hence the gigantic new Tube Phonos floating around (and maybe even a giant 300B preamp of similar ilk).

I have done this twice now, I waited until I had a good grasp on the sound signature of the Eros. I used three different sources, and in the end I prefer it with the choke. The change was subtle so I don't think I can either quantify or qualify the difference, I just liked the sound better with the choke installed. I think I might have to give the led bias a try, though the amp sounds darn good as is.

Cheers,
