Romy the Cat has found another room. I’ve started a new fiction project under my name, Roman Bessnow. The new work is at MutationsBook.com

Romy, from the anicdotes peppering this forum, it sounds like you have "done your homework" prior to choosing someone to share your life with, and you have done this at a time when you, at least, have already acquired some life experience. No doubt ...

Dear Romy, regarding your efforts to solve variations in mains power supply, there has been an interesting thread on RAT related to the use of toroids as power transformers that morphed into a discussion about the level of DC offset in mains power su...

At this point I am absolutely confident the there is difference in Sound between the properly sounding PP2000 that I had before and the “new” version of PP2000. Let juts for sake of illustration I will call it PP2011. The PP2011 is better soundin...

It was an interning event last night. The sound turned incredibly bad from electricity perspective. I did not have anything like this for a year or so it was very bad and it was clearly electrical. The PP2000 was workin...

Romy, thanks for the info on the chokes in the fullrange Milq.Today I have ordered more Milq parts this time for the power sequencing and bleed down. I decided to go for the relay sequenced bleeders for all four power supplies and figured I would be...

I have film in that position; I actually meant the 1000uf+ caps in the power supply. Hard to get those in film.... ...

I designed up a steel chassis for both the Fullrange and DSET Melquiades. Here they are screwed together for the first time. Then I have made sure all the cutting and drilling has been in the correct places by quickly putting the parts in their pla...

To keep with Romy's spirit of sharing his work, I have attached a file of VER 1.0 of the DSET Power Supply. There are quite a few differences to Romy's published schematics but it is basically the same beast. You will notice a lot of power transfor...

Nice job, KOT, and nice trace near clipping! It's always good to see a full, symetrical wave. Did you say you did or did not connect the halves of the 6C33C? Of course I ask because of the power you cite at clipping... Please remind me, what is t...

Fuses are seldom used in modern installations, but they are still widely available. "Better" breakers are also available from commercial suppliers, for whatever they're worth. It is true that "regular" breakers "soften" over time, and also in hot wea...

Have you ever tried a PUREPOWER device feeding something like the Torus RM20 which has a huge transformer and then out to the components? The Torus stores a lot of energy in those huge transformers. Do you feel this would have any merit...

The topic is absolutely idiotic but it is what it is. For the last week I was trying alternative power cords for my PP3000. Not that I was looking for some kind of different sound but I was trying a heavy shielded power cord with 30A power receptacle...

First they eased off and finally closed an old gas-fired plant, then they shut down the problematic nuclear plant. Who knows anymore if it's Smart Grid digital messaging, local "noise sources", or low current that's mucking up local power, but I can...

I have two balanced 240V/120V Equitech 3kVA step down transformers at the head of my system feeding my two breaker boxes. I have emailed PurePower several times over the last year asking if their units can accept 120V balanced power (+60V/-60V). I al...

HI all, my first post, although have been reading for a long long time and have contact with some members. Great site.Wanted to share with you my experience with a PurePower order. and my huge problem... I have read terrible things here before but I ...

Do not buy from this company. They took my money with no intention to ever deliver a unit to me. If you find a unit on the shelf in a store and it is functioning, buy that unit and take it home. Don't give Purepower your money up front. You will just...

Floyd,
Regardless your preamp uses output coupling cap you would still need a positive supply. Positive supply compensates the negative DC voltage at the amp’s input. Theoretically if you do not connect or disconnect the cable between your preamp an...

This is kind of funny. I got another B2 amp a few days back. It was near new condition, at least inside. As I plug it to drive my ULF I felt that it produces some kind of strange bass. I did not like it at all and it was very different then what ...

[quote user="jessie.dazzle"] The AK150 and 152 are not new creations dreamed up by Mike; they were made back in the day by Vitavox but nobody ever talks about them and I have never seen either. See the Unofficial Vitavox web site; AK150 = Catalog...

The past 6 - 8 months I have been living with very efficient speakers (~ 109dB/m/w) driven by low-power SET amps. The amps use 300B output tubes for about 7 wpc. On paper, this should be a match made in heaven. In fact, the combination is capable of ...

[quote user="Paul S"]Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter ...

There was a cool Russian-made tube GU-48. It is high-gain, high power pure direct heated triode with 300W on plate and 10A on carbonized tungsten cathode. I did not hear but it looks like something in the class of RCA 833 tubes. I think Japanese sel...

I keep thinking about power and how much extra power and gain I would need in a new room, Sure, it is not difficult to raise a white flag and do for SS amplification but I so would like to stay with SET amplification for my bass channels! I am lo...
|
|
What would I do if I move to a much larger room and the power of Milq’s full 6C33C would not be enough? Surely it would be possible to go for transmission tubes but they all high plate impedance and high voltage. If I parallel all my bass drivers and...

[quote user="hagtech"] I did bandwidth measurements at 1W. …. I should plot both 1W and 6W bandwidth responses. [/quote]
I always feel strangely disturbed when I see people specify SET response from 2Hz to 150kHz. Here is a practice out ...

MSA, I'll grant that greed is the force behind much of modern "technology", and I agree that good drivers are few and far between these days. However, I am not as sure as you are that an old Hartley driver could properly charge Romy's house with mus...

MSA, I have heard the McCauley 6174s, and I would own them if they weren't so expensive. But they still want a lot of power, because of the big motors and the exponential thing, and the size and nature of the space we are talking about.As you know, ...

Paul: You are completely wrong. While they may not have tested every unit in the past, they do now. They even send graphs of the testing results with the unit. I spoke with their engineer before sending one of my units back for a problem that turned ...

I agree i have been making mistakes even costly ones. I had taken the biamping route with cary and krell on B&W , and that was the purpose of getting both the amps, to get the best out of both ,,,,,,it turned out mixing oil and water,,,,,the most...
