modified jolida 100, mh cd-25, or audio aero prima

Hi Distortion, Congratulations! Look at the plastic inside. Black plate is black. All 5751 tubes beat any 12ax7 tubes IMO.

Just wait a month. The Jolida will increasingly give you ever more satisfaction.

I have been playing it about 24 hours straight and it sounds great, a little flabby in the bass, but very very sweet and seductive mids, especially female vocals. Strings seem to be strummed instead of just vibrating, I can actually here the pic clicking each string.

Looking at the tubes(5751) vertically, there are two horizontal plates about 1/3 from the bottom and about 1/3 from the top. These plates look like white painted metal. There are three or four odd shaped grey peices that run vertically from one plate to the other. They appear to cover a metal filament. Finally at the pointed end (top) inside the glass is a white metal halo mounted on a single copper post. But alas no black at all, at least internally.

The box says "JAN 5751 GE" along with "DLA900-87-C-0624" and "ESCM 33173 PN JAN 5751"

What you have are later date 5751 tubes. The two circular grey things you see are mica discs. The strange looking vertical pieces are grey plates.

Earlier (50's and 60's) have three mica discs, and usually black blates. There are early grey plates, but they will still have three micas.

The stock Jolida tubes are relatively clear sounding, and are sweet, but have a flabby bass.

If you have the money, $45/pair, I would get RCA tripple mica black plates. They are very good.

Distortion,

Any more comments on your new CDP? I am curious to hear, no pun intended, of your experience. Thnx!

I love it. I have about 110 hours on it, although some said it would take a while to burn in, I found it very pleasing at about 60 hours.

I have been using EH 12ax7eh's and really like them, vocals are awesom. Decay is sweet. A very black background. Dynamics are acceptable.

I tried some JAN GE 5751's (grey plate?) great dynamics, solid bass, decent vocals, but lost decay sweetnes and definately lost imaging. So back in the EH's went.

I have ordered Some NOS RCA 5751 triple mica black plates, on Muralmans advice, they should be in this weekend. I will come back and give my impression of these as well.

I only have one complaint, the case is a real bugger to open up. Seeing as you have to remove it to change tubes I wish it had been made easier to do. It is thick gauge steel.

The remote is a solid chunk of aluminum with ball bearings for buttons, awesome. FWIW.
