Stitch close to the lower edge of the turned-under lining, beginning at one side seam and stitching all the way around the bag. While they could all could be screwed up, all being screwd up in the same way is unlikely. Some residents of an Omsk apartment experienced a series of strangest "poltergeists" (see Vechernii Omsk from April 26. For those who have any questions about in which and how to work with straw bag round, it is possible to e-mail us in the internet site. and Omsk and Moscow TV broadcasts) at the same moment. For the Hastings versions, I would also suggest increasing the number of turns (maintaining the same ratios) further (e.g., 2X or 4X) to reduce the likely imbalance between the halves of centertapped windings due to unavoidable construction differences. The versions for the Hastings tubes will run at a lower frequency due to the higher number of primary turns. The Varian 531 tube shown has about the highest heater current of any common TC gauge tube so it should be no problem to adapt this to lower current tubes. Although everything worked correctly, I replaced the line cord and tube cords because they looked kind of ratty. As long as the heart of the unit - the actual meter movement and scale - is in decent condition, everything else can be easily and inexpensively repaired or replaced.

The manufacturer of this system uses a Hastings meter but has apparently removed the 115 VAC input circuitry and powered the low voltage electronics directly which includes a zener regulator and a 500 Hz oscillator (two transistors, toroidal transformer) to drive the tube from a 9 V battery (pushbutton activated so as not to run the battery down too quickly!) - I added an input for an AC adapter since portability isn't a major concern for home-built lasers and replaced the pushbutton with a good old toggle switch! This one had been modified to select between two (2) TC gauges tubes. Two of the CVT-16s are mounted in custom metal boxes as stand-alone units. It looks like something exploded and splattered the meter glass with hot globs of metal which took a few chunks out of it so that will need replacing and it has a very slightly meter but I expect it to be repairable.

I ripped out the original TC gauge circuitry since it was for a tube of unknown type and added an SG-TC2 driver for use with the Hastings DV-6M tube. And while you're completing your summer look, be sure to pick out a stylish beach cover up, a great beach book to read, and one of Ree Drummond's favorite accessories, a straw hat to protect your face from the sun. Materials: The first word that comes to mind is texture, as summer bags are often crafted with woven materials you find in summer’s best straw bags. Beautiful straw tote bag in bright yellow tassels and poms. Yuzefi’s black faux leather tote bag can be worn as a shoulder bag or a top handle bag. The top cookie, dusted with confectioners sugar, has a cutout so the preserves are visible. Observe the swirling from the side and from the top. With the resistor bypassed, this readout appears to work correctly with the DV-3M. The only required change to be compatible might be a resistor to adjust the heater current but even that may not be needed as the output may very well end up being within the adjustment range for the higher resistance of the DV-6M tube.

Hastings CVT-26 vacuum controller for the DV-6M TC gauge tube. Several Hastings CVT-16 vacuum controllers for the DV-6M TC gauge tube. After calibration using my DB-18 which is the reference tube for the DV-5, it now tracks my NV-8B (DV-8) readout fairly closely which gives me some confidence that both the readouts are accurate and the reference tube hasn't leaked too much. I picked up this unit for $16 including shipping (just the readout unit, no tube). This one (genuine Hastings throughout) uses an oscillator to drive the tube heater with a regulated AC voltage. Hastings VT-6B control unit for the DV-6M TC gauge tube. A battery powered control unit for the Hastings DV-4D TC gauge tube. A pair of Hastings control units for the DV-5M TC gauge tube. I have tested this unit with a DV-4AM TC vacuum gauge tube and after tweaking the heater current, it works fine. It is now happy with a DV-4AM tube. I purchased a DV-8M TC gauge tube from OE Technologies for about half the price new from Duniway (see the OE Tech High Vacuum Components and Equipment Page. The Scientific American Lasers can be built for around perhaps $1,000 each using scrounged equipment.
