[HBR] S-40B's and other tales

[William Hopkins]

Tom in Denver, 

Thanks for the helpful advice. In tool-and-dye country here in Rochester NY, I am sure I can find such a company. 

BTW, the Hallis S40A does have a front switch for the B+.

Very Cool. Yes, many of the xfmrs were rated right at the max of their 
performance. I sometimes have taken an old tube-socket and replaced 5U4's, 
5Y3's, and such with a pair of diodes, BUT - only in stuff where I have a B+ 
switch (like my HBR-11)... that way, the bottles have a chance to warm up, 
before getting hit with the plate voltage... it makes the transformers run 
MUCH COOLER, as you're not pulling that high current filament voltage for 
the rectifier, anymore. 

Yep - Halliscratchers came in all kinds of colors; all close, but not 
necessarily the same, as you found out. SimiChrome was "the thing" to 
polish up chrome and such on my British cars - works great. 

On cutting holes - if you can accurately draw up your layout, WITH accurate 
distances and locate the device holes (and types) where you want them, any 
CAD operated sheet-metal shop can punch it for you, and it'll look 
absolutely professional. Heck, they can even bend up an original, if you 
wish.
