[ARC5] 1957 book on Command Sets

Sat May 5 07:56:56 EDT 2012

Yeah..I have that book in front of me ..I thought it was quite good..why was 
it ''reviled''?..a lot on the txs and not quite so much on the rxs I 
thought..I'm not so sure about the 6v rx conversion mentioned..a lot of 
extra filament current for no improvement..tried it here and saw smoke 
first,hi!..back to the 12v in par..use 150 stab for the B+..not much 
difference with over 150..no dynamotor of course and the 12v is about 14v 
ac..only about 30ma on the B..nice cool kit..missing the 6 to 9mhz one..even 
have a 453-B with the BCB coils fitted   ..works fine on bcb with the 85kc 
if..a hacked one I suppose..a few other hacks as well..453-B on the side and 
454 on the top cover..very few of them appear to have been left alone at 
this stage..see one on ebay this am with no coils..another one with one if 
missing..caveat emptor,hi!
