This is a link to a CACHED page for a company called sound valves, which appears to be defunt, but which carried hard-to-find Dynaco parts. It's a good reference.

"Some guitars lose high end when their volume control is turned down. One way to solve this problem is to solder a .001 mfd capacitor between the input and the output of the volume pot (the two tabs that AREN'T soldered to the pot's case). This trick, borrowed from old Telecaster wiring, actually makes the sound brighter when you turn down.
"Changing the pots can also change the tone. In general, going to a higher value pot will make the sound brighter (changing from a 250k to a 500k, or from a 500k to a 1 meg), and, conversely, changing to a lower value pot can roll off high end."

I stopped in at my local Radio Shack to see if they had any clearance speakers. I ended up walking away with 5 pairs of varying sizes for a grand total of $16.00!

The "wallflower" speaker design using 1197's and 2 tweeters
Ahhhh: 98 db means 1 watt of power through the speakers produces 98 decibels of sound at a distance of 1 meter.

My ST-35 has arrived! I can't wait to get home and unpack it. Of course I have no pre-amp, so I'll probably try patching it through my integrated amp. Ideally, I'd like to build a Passive Attenuator.

Hey-hey!!!,
this looks like a single ended 50L6. This is similar to 6V6 in perfromance. It looks like the whole bunch of heaters are a long series string. There's not much point( IMO) to trying to fix her much. It will never have much power. Put the speaker and the amp in a lmall cab and you'll have your practice amp.

Douglas

This might be the most comprehensive basic electronics site yet
Ok, I think this is a good electronics tutorial that isn't just an ad for some guy's book.
And here's some circuit symbols charts I should print out once I get my printer working:
