Trying to gather and get my thoughts in order, in order to share them, I just remembered a recent mod that John Wright happened to mention specifically. While I believe John regards - and guards - as proprietary his ideas for reworking this gear, I a...

[quote user="SOS "]I've tried even placing a cheater plug on the PP+ unit and still get the hum. Why can everything be plugged into another conditioner or everything into the wall and all is dead quite BUT plug either the phono stage and or the TT mo...

[quote user="SOS "]First the other customers of PP that are having a hum problem are NOT my customers and use different components than I. Second it is not just the turntable motor but also get the hum from the phono stage when plugged in. Again plug...

John, it is interesting that you qualified application by the base metal used in the transformer. Here at GSC, many use "exotic" and/or "amorphous" cores, or perhaps high nickel content (or Si) for chokes. As it happens my own phono stage uses exot...

I once saw a phono stage that used sand diodes, and I have seen an interesting "tank circuit" amp that uses tube diodes +/- like a "buffer". Of recent "popular" amp designs, I have seen a lot of triode PP, but I think this is the first SE pentode I h...

I have a PDF file of the manual if it interests you to read it, I can email it to you.
The unit weighs 80lbs, uses 6 6sn7's.
What I found a little odd was the spec for the phono is it says : MM Phono Stage Gain: 64 dB at 1 kHz
I own a Expre...

I just completed (DIY!) several "factory" "upgrades" to my SE phono stage. While I had no frustrations with the unit, I have been reading designer Kevin Carter's careful explanations of the changes he has worked out over the past few years. These mo...

[quote user="rowuk"]How many sources do you currently have? If you are building a phono corrector, make it for 4 volts output. If you have a PC for digital playback, there are good DACs with more than 2V output. That would leave a tuner to pimp - cer...

A Federated Mike started his new venture ultimist.com, the portal where he feel people would like to go to do “purchase research”. Those poor audio dealers do not get that someone might have interests in audio outside the brands, shopping and nee...

The iDAT-44+ just got back from a visit with its dad, John Wright, to repair an intermittant fault and to work his current round of "upgrades" to the sound. Also, over the course of re-integrating the fixed and improved iDAT, I re-thought the way I ...

[quote user="outopos"]Hi Romy,I am new to your site. I have read some of your postings (including other sites) with much gusto.For the digital LP recording, I am (was) tempted to do the same, but given the fact that I have absolutely no personal ...

Tm I ma glad that your “Manhattan project” is over as I was a little scared….
Well, I always thought that I have an open mind and I would not mind to try it. Unfortunately I do not do SS as I afraid of it electrically…

I have posted about some of my recent experience with longer "naked" HF ribbons in Romy's "Water Drop" thread. Here are some observations that relate these drivers back to the ML2s, along with some other recent ML2 trivia.My speakers are listed...

[quote user="Paul Costa"]Thanks for your reply.I am in the market for either a new pre-amp or phono and line stage.I know they need around 47k for optimal loading, but what else might I be concerned with.Did you have a look on Agon at the two there.&...

[quote user="guy sergeant"] I've usually found valve rectifiers to sound preferable. [/quote]
For HF channels only. Still with shaft switch diodes and properly implemented input choke filters there is not advantages of tube rectification, quite oppo...

[quote user="guy sergeant"]Sorry, I have a better understanding of the purpose of this exercise now.Are you making 2 new platters or is one to be the existing Micro Platter? [/quote]
Nope, juts adding RX-5000 platter and base to the existing RX-8000...

Well, it might be some kind of misunderstanding… The XV-1 was their flagship product in end of the 90s and it cost I believe $1.6K-$1.8K retail. The reasons why I know it certainly because I had a few quite credible people at that time who stro...

As I play the old-but-new-to-me ML2s more, and as I slowly replace tubes, performance has changed a lot, and all for the better. Understand that I am not really talking about the ML2s, but about the sound I am getting, which is so different and...

[quote user="Romy the Cat"]I think that you did not exactly my version but made some modifications; I do not know/remember what they were. [/quote]CCS heating of the tubes based on LT337A, 2x0.47u+470K at the output,my filtering is a bit bulkier at ...

It is absolutely impossible to say how you need to organize grounds
to be “right”, it is not to mention that you leave in country (region) where
the power destitution lines might be different then in other country. For sure
there is a compliance w...

I do not mean to be negative and criticize Romy, but he is wrong on surround sound. It is the implementation and not the concept which should cause vomiting, like with the vast majority of two track recording which are unlistenable. With the rig...

[quote user="Romy the Cat"]Again, it was very interesting, but… Let agree that methodologically you did not try Placette as it performance was masked out by you need to use your Neurochrome buffer to get gain. Your chain will sound as the worst eleme...

Thank you for the comment on this amp, this is my first time of using the 6C33C tube, I decided to build this amp after reading about the Melquiades, this amp is just a quick experiment on the 6C33C sound, since I have...

Lamm introduces a new product, the LP1 Signature phonostage. Vladimir was planning to do it for a long time as his parley into “reference” series and after his from my point of view failure with LL2 phonostage.

It is not a the thread about Allnic but LCR RIAA correctors, still there was something expressed in here about the Allnic LCR phonocorrector… and I feel bad about it. It is not that I don’t think that Allnic LCR phonocorrector deserve positive m...
