I would be very hesitant switching that kind of voltage. Are there any markings on the failed power supply?

Split printing will work great. You only use one grid at a time and you have a built in stabilizer for each which will assure repeatability. They should have made this a feature, since the...
Thanks for the kind words!!!
One other thing, those two gold 1.2K ohm, probably 25W resistors are heaters. Neon is most efficient (most light output) at a temp of about 112-115 deg F. The round...
I have done a lot of research on the neon VC heads, both Zone VI and Aristo. The HV supply in the Zone VI head is a solid state dimmable neon power supply. The older iron core transformers were...
Yes you will have to do surgery on the unit to add dimming. The BuckBlock LED driver has to go between the power supply and the LEDs. Look into Rosco ND filters. . . they are inexpensive. . . but...
You need a constant current driver. I have used these for driving multiple high power LEDs. . . the data sheet will give you more info. . ....
We pick up the smaller Esterly Speed Mat cutter several years ago off Craig's List. . . really like it. . .
Thanks! My wife just closed the darkroom door for a day of printing some new 4x10 negatives. . .:D
Here is what I have done with the 8x10 Zone VI VC Head. . .

We had a great time. Thanks everyone!!!
Great time today folks. . . and a good turnout also. We must do this again!!!
77mm fits most of the large lenses I carry, like the 55mm G-Claron and my 24" Artar. . . the other lenses take a 67mm. So I only have to carry two Lee mounts. . .
Hi Jim. . . the 30" Artars we have came factory with a DecoRing without threads. We had new DecoRings made with internal 77mm threads for Lee adapters. I believe that most Artars have non internal...
We have recently discovered that Ries Tripods has been sold and is now in full operation under new owners. I know there is another thread about their Intuit commercial, but here is more info on what...
This will be great!
5:00pm today Fort Worth reporting 97, dew point 74, Heat Index 108. . . Welcome To Texas!:(
Glad this is an indoor outing. . . suppose to be HOT Saturday.
We will be there. We do need to get out with the group before the heat sets in. Hopefully we will have a good gathering Saturday. See you guys there.
Thanks Michael for the photo and a big Thank You to everyone that joined us today!
Hope to see you soon Paul!
We would like to invite everyone to drop by and see some of our latest work on display in Dallas. We are traditional B&W photographers working exclusively in the wet darkroom. We work with LF and...
This is a common problem with ULF holders that do not have a relief to get your fingernail under. Here is an easy fix. . . drop by your local music store and purchase a few thin guitar picks. ...
Thanks Jim! Bought this house in '96 and built the darkroom almost before I unpacked. It has worked very well for us. . . the only complaint is we could use a longer sink, this one is 10' 4". . ....

Always build the sink as large as the room will allow. . . then add six feet for good measure!
That enlarger looks familiar Paul. . . NICE!!!
Sandy. . . I experimented extensively with making acrylic GG several years ago. Back at the same time I was trying to find something off the shelf, possibly rear projection materials, with no luck. ...
Anyone done any research into rigid (polycarbonate or acrylic) rear projection screen materials for LF ground glass replacement? I poked around several years back and everything I found that might...
I have no bone to pick with anyone. . . I was just a little taken to see such a seemingly negative statement made in a very good article. I am perfectly satisfied to call the D vs A thing a draw and...
I was taken by the provocative statement suggesting that a digital print is a 'poster' would stir some up. I know some people that would be ready to load-n-lock over that statement.
Has anyone seen the article by Patric Alt & Larry Scher in the current issue of View Camera Magazine? Specifically, the last sentence on page #20. That should be enough to start WWIII in itself! ...
That is me with my DIY (built from stuff I had laying around in my garage workshop) ultra-light 11x14 camera (13.5lbs) with custom-built backpack sewn by my wife, who also took this snapshot in Zion...
Fun day everyone. We stayed till Michael arrived abut 3:00pm. . . by about 5:00 the light was really nice till sunset. Just had to deal with the heat and a little wind. Enjoyed the day...
We met before at the Penn Farm Parking Lot. I would say somewhere between 7:30-8:00 am for us.

Might be different over at the park. I don't see much color here in S/W Tarrant County. You never know.
No fall colors here. Hasn't been that cool. It was Sat before last that it was in the 50's all day. Needs to get a little cooler and stay there for a few days.
It was really nice last Saturday. . . In the 50's all day.
For those that have seen the article titled "Last Bell Factory in America" by R. J. Phil in the current Issue of View Camera Magazine (July/Aug 2012). Here is the followup story on the Bevin Bros....
We'll be there. . . plan on bringing a picnic lunch and staying for the day. Hope it is cold that day!!!
All I can say is, Dang that was good!!!! Great to see everyone!!!!!!!
