Jon,
I like the transformers in there. Is the lower one the BC-610 plate unit? top one for filaments? reminds me of the LV power unit from an IBM minicomputer I scrapped long ago. Lots of wires, more than enough 10V +/- for many tubes.
BC610 transformer can make lots of power, more than enuf for a 3-500, you will get good regulation in spite of the transformer's high winding resistance. I made a nice 2M linear amp using one of those and two 4CX250s in cavities. It never lacked regulation, ran a choke input setup for 2KVDC/500mA.
For screening on the RF deck, some hardware stores offer perforated brass or aluminum sheets in large sizes. Some of the perforations are ornate.
I love the lighting scheme. Moreor less 'monochromatic' or definite-color light makes very striking effects. Black light is great. If the "BLB" filter is good, there will be little lvisible blue light but lots of fluorescence. If using plexiglass, get the UV coated stuff so the UV won't craze it. A deep red in combination with black light is sriking too. I look forward to the visual art of the results. Going with just Black light, painting the inside flat black and outlining the edges of the components in some fluorescent paint colors would be very striking even with the 3-500 washing it out a bit. There is color filter sheeting inexpensively available from GAM gamonline.com and each type shows a spectral response curve so you could tailor the light. A blue/UV one i used blocked everything from a 2KW tungsten light and gave a very deep blue 'night time' effect on stage.
As far as heavy amps. - the thing could qualify well in the annual heavy metal rally promoted on this BBS, where a high lbs. per Watt ratio is desirable.
Where do you live that scorpions sit in trees? That's scary.. I hate finding them in closets and woodpiles. I thought all i had to worry about dropping from trees were caterpillars..
Dennis,
having so many BC610 iron, have you considered putting an equalizing choke (a 60Hz 1:1 current balun) in the primaries of two, and then parallelling them? nutty idea but big variacs were parallelled that way.
yes that huge heavy iron, it's beautiful; I'm happy. Duncan says
3200V@1.2A but it will do more current and with a C input filter, 5050V@350mA and 4500V@2A (ICAS there). That amp needs 5KV on the plates to make the 2KW. 3200 will make 4-1000's sluggish - maybe 800-1000W.
I believe even though it will not fit well it's going to be the plate iron for the 2KW audio amp. I been getting bids to refurb the output transformer. BTW did you find the front control panels, glass, anything else and maybe also the LV iron for that monster? Think you had found that stuff. Sam has found the chassis', but alas the 4x1 sockets are missing.
