Every Halli I've ever seen was rather crudely built. The front panels
may be nice but the wiring looks kind of amateurish compared to a
Fender amp or a MacIntosh from the same era.

What's wrong with replacing the paper electrolytics (as long as you
save the old bad ones for some insane person who would prefer a
confetti blaster)?


Sure, if the owner wants a well-working, reliable radio. But, at that
price, it's not really a radio any more. It's a piece of history, a work of
art or maybe a fool's investment waiting for the greater fool.

Phil Nelson has some pictures of the insides of his SX-88 on his website:

Actually, I kinda prefer the rat's nest wiring approach. Lining up the
wires and components neatly almost certainly increases the inter-component
capacitance and I don't mind if they spent the money where it can be seen
rather than hidden away.

I'm not advocating right-angle dress for RF point-to-point wiring,
Just the stripping and soldering on some Hallis looks quite sloppy.
The bandswitch frightens me away from them more than anything else.

Frank Dresser,them old tube analog Radios are the best Radios in the
World.Screw all of them new fangled pieces of **** digital so-called
"radios"! Hey,last night,after I took my girlfriend home,I saw an
article at www.rense.com about marconi and Nickola Tesla.In my
opinion,Nickola Tesla invented Radio.Stubblefield was a pretty smart old
guy in Kentucky too.Most upstarts nowdays don't know **** about Radio.

The straight line point to point is the shortest distance between,
which the axial components must reach. This is done to reduce the
inductance of the path and yes if the paths are not parallel to each
other then mutual inductance is also reduced between them. If the
parasitic inductance of the component paths is to high then the
circuits will not work.

There are many techniques to reduce parasitic inductance like grounding
rings around tube sockets. If a resistor to ground is needed to bias a
tube element then it is a short distance from the tube pin to ground.

The higher in frequency the circuits must operate the more critical it
is to keep this stray inductance in check.
