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...

RCA LSC 2605; stereo.A very nice recording taken from "the best" of Rubinstein's much-ballyhood 10-recital series, as noted. Some Debussy is included, which is why I remembered it at this time. In this case, Rubinstein seem...

[quote user="RonyWeissman"]Attentuators plugged directly into the RCA jacks sounds like good solution for balance control[/quote]Do not forget that you do not need the attenuators but juts one attenuator that you would plug on right OR on left. Also,...

A strong second-recommendation of the 1977 Horowitz recording of the Liszt(RCA 12548 here in France). It is a superb sounding LP as well. For some reason I can't listen to anything Argerich lately, maybe it's because everytime I have ...

I have coved this subject in past. I was not able to find a solution how to add resistors to change loading and how to make it to be switched that would not degrade sound. So, my own phonocorrector has no adjustable loading. If I need to do it I woul...

as it sounds now, and what seems to be the issue. Why not contact DG and find out what THEY have to say, that'd be educational, no?!There was this saying about DG: "Good news, DG stopped making vinyl!" The bad news is, -- now they make CDs!!I'd put m...

RCA LSC-2401 (stereo)Despite truly terrible electricity today there were some amazing moments from this LP. This is the first time I have I heard this record via my present system, and it warrants a recommendation despite the unbearable sound (due t...

Hans Vonk is also my favorite... It was Slatkin that built up the St Louis Symphony orchestra,,and passed the batton on to Vonk when he left,, VONK and the STL.,,,did a special concert for PBS TV of Carmina Burana,,,The chorus and soloists really ha...

[quote user="Romy the Cat"]Yes, the layout kind of not optimum. You might try to lay the transformers sidewise and to make the RCA atop, above the transformers. Still, I hope you understand that your hum has very little to do with layout. Properly gr...

N-set, it is difficult to say anything without seeing the circuit. I think that you did not exactly my version but made some modifications; I do not know/remember what they were. The major think that I see at your picture is that your main grounding...

Today a friend of my sent me a link. I have no idea who it is, look like an Asian installation. Since it is WE-like system it most likely somebody from Joe Roberts crew, or the similar audio-bullshiters. I am sure that the owner of the system wil...

There seems to be a standard 2.7V option for you:http://www.phasure.com/index.php?PHPSESSID=rdq01o6tv8ed20nii15hjqnjb0&topic=1560.0"Output level for Single Ended Mode (RCA) is 1.5VRMS (-3dBFS relative to normal Full Scale). Output level for Diffe...

Oh go ahead, be my guest! You seem to have a proper handle on the situation. As for "designs that have been known for decades", I know someone who says that there's been nothing new since the RCA Handbook of the mid-Forties (IIRC). Yeah. So now what?...

Thank you for the description. How they are sealed is what I am most curious about. I've tried a few different techniques to seal fluid in the tubes during my cable experiments. Does it look like they simply injected a clear silicone, terminated to R...

From the perspective of pumping of atmospheric pressure the ALE bass drivers might be more capable transducers. It or might not be so as well. To get 40Hz at 110dB in 5” it would take some excursion. I am sorry but you can’t bend the law o...

guy, i noticed you've mentioned a DHT 10Y linestage.i'm wondering what are your thoughts if there is a relatively easily obtainable (in say lifetime quantities:)) DHT (or triode stripped DHP or DH tetrode a la 307A or 807) capable of d...

Adrian, I agree that SETs generally have issues such as you describe, and moreso the small ones, especially at the frequency extremes, and at saturation, which tends to occur all too soon, IMO. But I have not sourced these problems back to...

Ah, methinks you do Steve Schell a disservice Romy. He suspects that my RCA drivers have hairline cracks in their paper voice coils (certainly, one of the drivers is making strange noises) so I am getting his new replacements which are made of carbon...

Paul, Everyone has their personal favorite on the 45... I have several RCAs... still prefer the Sylvania over them. Also, I've never seen a 45 with anything but a black plate. RCA did make black plate 2A3 tubes which are more rare than their gray pl...

Today I OCD'd my way through every freaking connection in my system, cleaning all connectors, daubing them with dielectric grease and re-connecting them. Included were electrical plugs, RCA jacks and plugs, tube pins and sockets, cartridge pins...

Thats interesting... When Slatkin was music director and conductor,,The St Louis Symphony was voted No#1,, i dont know how that standing came about..Some politicle shananigons i presume.. Most of the Slatkin recordings were produced for RCA at that t...

Hi,[quote user="Romy the Cat"]All that I need was some kind of vacuum tube buffer that would have no-gain of a very low gain and that would be sonically completely transparent.[/quote]Completely transparent is very hard to do. Try the following:6AS7 ...

Something I see a lot of in studios is the "distribution amplifier", that joins and splits the audio (and/or "video") signals into any number of channels. I believe I want buffering, but I am not ready to track and impliment the "balanced" configura...

I spent some of yesterday listening to the 8th and 9th from this set.
Recorded in mono by RCA in the early 50's I really like these performances. As a bonus the recording quality is good too. Does anyone else know them?...

I must confess that I don't have a lot of time for Heifetz's recordings - I find him too cool and aloof (even in the Sibelius where such attributes might be expected to be virtues) - to me he sounds indifferent and unresponsive to the emoti...

This music is so lovely, I don't know where to begin. It is sung here by the Robert Shaw Chorale/RS conducting; Saramae Endich, soprano; Seth McCoy, tenor; Claude Frank and Lillian Kallir, pianists.I find the themes and the harmonies ...

What an amusing little peace! I had it for a while along with the rest of my Munch recordings but I never paid attention to this César Franck’s work until recently heard it on radio. It is 1962 recording and Boston lead by Charles Munch. It was 3 yea...

Well, Kapell is another of those "cult figures", whose legacies seem to take on lives of their own. Once the worshiping of them becomes a self-sustaining industry it becomes difficult to have reasonable discussions about them anymore. ...

RCA LSC-2581, 1962Here is a worthy performance and a nice stereo recording of a wonderful peice of music.Very rich orchestral sound is so appropriate for this music. Reiner, Van Cliburn and CSO at their respective bests.Mature playing on everyo...
