Just finished my PR McLux head used an R2K and a downboy 500. This was my first "real" mod, other being changing the emitter in a KL1. Radioshack did'nt even have a fine point soldering iron or wire thinner then 22 gauge! but i got throught soldering the leads to the downboy with no issues, then glued the DB into the ecan and let sit overnight. This is probably a no no but i used JB Weld to glue in the DB. Rather then grind away the ecan where the "holes" for the leads are i just allowed the JB Weld to cover all the holes. Then I was getting ready to remove the R2K from the star and i noticed that on one tube of the JB Weld is says "steel" panic sets in.... is this crap a conductor? ahhhhhhhhhh. A quick visit to their website sets my mind at ease says it a great insulator.
Moved on to the emitter, desoldered it and got it off the star. lapped the underside and soldered it to the PM emitter board. Then trimmed off the tabs on the PM and got it to fit real nice in the PR head. Next day epoxy cured, soldered the ground wire to the ecan potted the ecan with AA and put it in the head.
Only problems came next, the 22 gauge wire was hard to bend into position to solder onto the PM board. Finally got it but lost some insulation off the leads, no sweat coated them generously with nail polish then AA. Put the benzel on crossed my fingers and hit it... Bright light and NO magic smoke. YEEEEESSSSSS
Anyway PR head is amazing WAY tighter beam then the LP Fraen and sidespill to boot!!!! Need to gather some funds to do this with a Lux III and a DB 750
