Dear Paul, I doubt whether you have any Thaedra II boards in the unit. Also, with the exception of the first 100 units which had a head amp servo that was designed by Bascom King, and subsequently

Hello James, The boards in my Thaedra are numbered as follows: Head Amp: 324C Phono 2 : 523 Line : 522 Mode/Fil: 327D Tape Sw : 325C Power : 321C Since it would appear that the boards have gone

Dear Joel, The P250 is the commercial version of the similar 2500. Basically only cosmetic differences but it still uses my fundamental circuit design. As far as mods go, I have attached my

I'm awaiting delivery of an SAE P250 which I purchased mainly based on another's raves about his SAE P500. Does anybody have any experience/ comments/opinions regarding the P250? I'd also like to

Dear Paul, You hit the nail right on the head. I've felt AND said for years that this industry in certain regards is taking giant steps backwards. Mostly, it is because these idiots do not HAVE A CLUE

Dear Paul, Yes, all "inputs" on the Thaedra are shorted when not selected by the selector switch EXCEPT the tape copy and monitor inputs and output, for obvious reasons. James Paul Anthony Bigelow

Dear James, Does the Thaedra short out the unused inputs? (I could easily measure and confirm but I haven't -- yet) What was noticed was that the Mk VI FM audio display disappeared when the Thaedra

Dear James, My apologies. I do not mean to give the impression that I am prying for a real technical, indepth discussion or any information that would be proprietary. I am just interested in audio

Dear Paul, The problem that I can see here is one of giving away (for me at least) 40 years worth of acquired knowledge.Why on earth should I tell the world what I've learned over the years so they

Dear James, Thank you for the response. I would certainly agree that a learning curve was necessary to bring the transisitorized equipment to a high level of performance but what my inquiry was about

Dear Paul, I hate to belabor the point, but would you like to drive a Model T Ford today with its planatary drive and spark advance, etc. I think not. The early years of solid state from the mid 50's

Dear Armin, Forget about HK. I wouldn't hit a dog in the #$% with the stuff that they made. Their emphasis has always been Japanese through and through. The only thing that they ever did in the last

Dear Paul, Actually, you are right about Marantz. They did stop designing tube stuff in 1965. However, that's when Sidney was developing the very nice Marantz model 15 power amp (1966) of which I was

Dear Bob, If you can wait a bit, ATI (SAE's successor company) is coming out with an A/V processor that will have a built in LCD color TV monitor. Pretty slick. James Bongiorno desertfox wrote:

Dear James, Most early solid state equipment, as a class, seems to be viewed with much disdain by current audiophiles. If early solid state is as bad as many audiophiles state, what do you think were

Hello James and Armin, To me, anyway, there seemed to be a point in the very early 70's where Marantz sort of stopped being "high end" and more "consumer grade". It also seemed to me at about this

Some of the HK Citation product line was pretty decent as well. I don't really think Threshold has been around since late days of tube era. Armin Paya Paul Anthony Bigelow wrote:

Hi! Guys. I was thinking about buying a Marantz A/V 9000, or a Rotel RSP-985 A/V Preamp for my home theater system. I would like to get everyones opinion on these two models as to quality. Or any

Paul- Late 60's was pretty much McIntosh, Marantz, Crown, perhaps Fisher to a point - by 72-73 SAE, Phase Linear and Audio Research were there- - but the Japanese were opening up the consumer market

Dear Paul, Substitute Marantz (tubes) for Mackintosh. James Paul Anthony Bigelow wrote:
