[QuadList] Restoring 2000's

Wed Feb 3 15:22:41 CST 2010

Hi Park,

Everywhere that I worked in the 60's, had a GE dishwasher, and used water soulable fluxes and every board would process through the "dishwasher" as the first stop after wave soldering. In 1964, I souped up a "Dee" wave soldering machine, increased the wave height from 1" to 1 3/4" and changed the major build processes by eliminating hand soldering of contols.

Hi George,

Thanks for the kind words.

Yes, I am a believer to get everything clean before rehab. Easier to spot damage. I understand Tek had a special dishwasher they used.

Yes, I have taken Quads outside and used compressed air to blow them out.

I also think connectors are 80% of a problem so I clean them and use DeOxit. 

Best,
Park

Wish you were in Bremerhaven where the main announcer was so nasal and obnoxious it was almost offensive to listen to him, thank God for Radio Lux and some of the pirate stations floating around the channel and North Sea as well as R-390A's and big antenna farm so as to listen to some of the NYC stations.  The "Duty" announcer at CBS is a fellow named Tom Hair. He started at AFN, as I remember in Turkey.  Before CBS he was the voice of ESPN.  He is a good friend, great guy.

As you may know AF was refurbishing quad machines, bringing them up to Ampex standards or better and making them look like new, they even repainted them with Ampex paint. I would troubleshoot them, line them up before they were shipped out.

They  scrubbed them all down and put them in the oven at 120 degrees for a couple days.  After that they looked like they just came out of Ampex. The boards all worked just fine, unless they had some bad components on them to start with. I wonder if they could have just put them in a dishwasher.

He agreed.  All I did was pull the CRT out and the HV P.S. out pulled the fan and scrubbed it with Cascade and dried it out.  When I put it all back together it worked fine, I just put some lube on the switches that needed it did a small alignment by the book.  I guess you know what those scopes looked like, all those parts, wired in, no PCB's etc.

When we put the house in here in Port Jervis I made sure we got a stove with a "Standing Pilot" in the oven as when you close the oven door it stays around 120 degrees in there and does a great job.  I suppose a 100 watt light bulb might do the same in a non pilot equipped stove.

It was realy filthy, covered and filled with dirt, crud, dead rodents, you name it.  It was going to go to Archives which is across the street and I was affraid they wanted me to get it working.  I had it brought into the "garage" on 56th St and the next day I brought my leaf blower in.  We rolled it onto the sidewalk and in front of half of my shop laughing their asses off, I blew it all out. It really did a great job, it came out real clean, much to the dismay of my colleagues. I highly recommend this method for any real bad machines.  You could probably get away with hosing it down and leaving it in the hot sun to dry or even put a machine in the back of a pickup and drive thru a car wash.
