<div><FONT face="Arial, Helvetica, sans-serif">Hi Ted,</FONT></div>
<div> </div>
<div>Guess the fotos made it OK.</div>
<div> </div>
<div>The machines were almost working by the time I found out about them, the only problem was one TU motor was going crazy due to a shorted SCR in the rear of it.</div>
<div> </div>
<div>Fotos were tooken about a year ago, a month or so before I retired.</div>
<div> </div>
<div>The thing under the 1100A is is what we called the "Works in a Drawer". One of the Engineering geniuses thought it would be nice to have all the electronics behind the deck in a pull-out drawer, so all 40 or so machines were so modified. Don't ask.</div>

<div><br>
</div>
<div>Thanks for your post. It's <I>exactly</I> the kind of thing the QuadList and website is intended to foster.</div>
<div><br>
</div>
<div>Did you have any problems bringing the AVR-1's back on-line after years of disuse?</div>
<div><br>
</div>
<div>You <I>can </I>attach photos and PDF's and other types of files. Attachments up to 1K in size will hit the list without issue. </div>
<div><br>
</div>
<div>Larger attachments hold up the e-mail and alert me to check the posting, which I then can look at and send on to the list.</div>
<div><br>
</div>
<div>What vintage are the photos? Interesting to see a Sony BVH-1100 still in service. </div>
<div><br>
</div>
<div>Curious about the item in the cart that's below the 1100 and above the BVT-2000. Do you know what it is/does? Looks like a couple of rows of hard drives in an array... kind of an odd thing for a 1" machine.</div>

<div style="CLEAR: both">Hi Guys,</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">I just had a visit by Mr. Jim Snyder, I guess most of you know him and the big job he has ahead of him. I told him I would pass along tips when I would pass a "Brainstone" about quads, and do it here. If anyone would like to add to anything I put out, please do, or if you want to straighten me out, that's OK too, don't worry, I don't insult, especially if it will help Jim.</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">Not too long ago I had a reel servo problem on an AVR-1. In troubleshooting it I wondered if all the lamps in the Vac Cols were lit. Problem was someone had replaced the lamps with IR Led's and I couldn't see a damn thing. (Not sure where these machines came from, CBS Archives put them in years ago, had Ampex install them and didn't tell anyone across the street in the Broadcast Center. And they weren't used for years.)</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">I recalled that most digital cameras are sensitive to IR, so I brought my digital camera in and sure enuf there were the little lights, all lit up. A couple days later I found the problem was in the Power Supply feeding the "Servo Preamp".</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">The led's were a good idea, except you can't see where the tape is or if they are lit. Apparently the "Solar Cells" are sensitive enough to react to the their light properly. Years ago, I replaced the lamps in the Vac Cols in all of the ACR's at CBS, all 6 of them, but I used hi inten. visabile red led's. They worked just fine and really looked cool, like something from outer space. Never had one fail either. They were very stable also, never had to adjust the + and - 5V on the preamp board.</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">I am attempting to attach a couple fotos of this situation to this e-mail, not sure if it will make it to this site, but if not if anyone really cares, just send me an e-mail, I will send them to you directly.</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">Another problem cropped up, some Bozo broke one of the glass covers in one of the vac cols on the other AVR-1. Needless to say these are about impossible to replace. I tried many glass dealers even a scientific glass outfit in Clifton, NJ and no luck. One of the guys brought in a piece of just plain ground glass cut to the right size and it seems to be OK! (so Far).</div>
<div style="CLEAR: both"> </div>
<div style="CLEAR: both">Hope this is interesting, if not I think you all have "Delete" buttons on your keyboards, don't hesitate to use them. (HI) If it is good, perhaps someone will put ME in for a Nobel Prize.</div>
