Hello, What constitiuted the U.S. "high end" in the late tube, early transistor days? From what I can remember, it would be SAE, Threshold, GAS, McIntosh, and Audio Research. Who else was present at

Dear Paul, If memory serves me, I think only a 1000 Mark VIB's were made. Actually you would have to check with Morris on this but I think I'm right. Just as Sid and Dick at Marantz spent a huge

Hello, What a joy it is to have tuning as smooth as the Mk. VI. It has ZERO play. NONE. No vertical movement, no horizontal movement, none in or out. ZILCH. It is the only tuner I have ever

Dear Paul, As I said before, yes there are two filter blocks in the IF of the Mark VIB. One is a four pole and the other is a six pole. The reason for having one in close proximity to the front end is

Hello, There are actually two Filtech units inside the Mk. VI. One unit appears to be located on (I assume) the "IF board". Another, different, unit is attached to the "RF assembly". This "RF

Dear James, If these tubes are available, I'll find them. Since these tubes are *probably* not SAE specific, there must have been other applications. If it can be determined what else the D7-200GH was

Dear Paul, SAE did go all out with the VIB to the best of their ability. The tuner really was a beautiful piece. As I've stated on these pages before, I myself am looking for one as many years ago, I

Dear Paul, There is an old saying:if it ain't broke, don't fix it. Regarding the intensity control, if it works and is functioning, leave it alone. This is one of those "direct" interaction controls

Dear James, You are correct about the "spot killer". While not readily apparent with the transparent smoke cover in place, there is a faint residual dot visible with no signal present with the cover

Dear James, Thank you for the reply. I would not undertake an RF alignment on this tuner. What I would like to do would be to determine if the the Intensity control "fix" was done properly and attempt

Dear Paul, I have all of the schematics for the Mark VI tuner however, I hesitate in sending out tuner information due to the fact that without EXTENSIVE knowledge, it is so easy to completely screw

Dear Paul, First of all, I can't see how anyone in their right mind would remove the gorgeous rack hadles that I designed for the unit. Most assuredly, this is one of the late units. There is no

Dear James, Thank you for the response! When it rains, it pours. I state this because I have located a Charlie tuner. It does not have the handles so I assume it is a later one. The serial no is

Hello, IMPRESSIONS I just received my Mk VI tuner. Am I impressed! Maybe my other tuners are garbage (probably) but this tuner sounds great! It has many of the sonic qualities of my Fisher 400

Dear Paul, The "Charlie" was indeed a model 700. And it did not use nixie tubes but rather LED display readouts. The faceplate was available in either black (to match the Andromeda amp) or in Gold (to

Dear Kenny, Please be aware that NAD gear is made in TAIWAN and for the most part, might be considered the high end of the "low end". That is, you get what you pay for. When gear is priced dirt cheap,

Hello James, Is the Sumo Charlie also referred to as a Model 700? Does the unit have an aluminum or black front panel or was it available in both? Did the tuner always use the nixie tube for the

Dear Paul, SAE wiring layouts were absolutely firs class, at least when I ran engineering. I think that for the most part over the years, the construction quality of SAE was First rate. James

Hello, The Gasworks web site at http://www.gasaudio.com has suddenly become unavailable. Is anybody else experiencing a problem? Best regards, Paul Bigelow

NAD is probably one of the best companies making equipment that is way above par.
