[time-nuts] LPRO in TM500
Dave, The modules I was built went into the TM501 single slot frame. I used the line voltage jumper to raise the voltage from the bridge a bit. I also used a 6800uF capacitor on the bridge output. I used an LM317 regulator and set its output at 22VDC. Hope this helps! Corby Senior Assisted Living Put your loved ones in good hands with quality senior assisted living.

Re: [time-nuts] LPRO in TM500
Hi Traditional Efratom circuits would run down to 19 volts without real complaint. In fact the power dissipation was less at the lower voltage.I don't know how much of that they carried on into the smaller versions.

I'm curious as to what voltage regulator you used? The input and output are so close that I'd thought only a dc-dc converter could do it. Happy holidays!

If I remember correctly I used a thick (about 1/8) aluminum plate most of the length of the module as the mounting and heat sink. The edge of the plate was attached to the module with screws and aluminum angle brackets to allow the top and bottom of the module to also help with the heat sinking. They all worked fine. If you use a dual wide module you will have more room to work with and maybe could used a finned heat sink. The edge connector used was one from a guy on ebay that made custom ones to use with TM500 Modules. You just screw it into place in the module using the existing holes. For power I paralleled the two 25VAC windings, fed them thru a full wave bridge into a largish capacitor, and then into a regulator set for 22VDC. The regulator is isolated with a silpad and bolted to the top frame of the module. The 10Mhz output is on the front along with a lock LED. Hope this helps.
