As an aside - nobody 'works' for wikipedia, all the articles are just written by people who think they know enough about something to write an article. Because of this, you get some situations where enough people think ptp is toggle-board style construction, and it ends up in wikipedia. There are TONS of sites that reference wikipedia so you search for something and see tons of results that match, but they're just the same article repeated. A lot of those sites say 'from wikipedia' somewhere on the page. Even with that problem, the number of errors in wikipedia are similar in amount and scope to those found in encyclopedia brittanica. You can use it as a good source, but every now and then be prepared to doublecheck. If you think the article on PTP is erroneous, you can edit it to reflect the true meaning. If you do, add a note on the discussion page to reflect why it was edited so some well-meaning person doesn't come along and undo your hard work.
The good thing about amps designs that use circuit boards instead of printed circuit boards is they can be repaired easily, and if the layout on the board has been carefully thought out you can work (sketch) out the circuit pretty quick.
If it uses an etched track for ohmic contact it aint point to point is an easy way to sum it up, just thought I'd add that to the other correct explanations.

if you go to the victoria web site Mark mentions in a couple of places the sonic impact of the ta board construction material on his amps associated with voltage bleed among other things. everything is a compromise in the end...except good tone

About 15 years agao there was one of these old Ampegs in a pawn shop here. It was painted black and somebody had added 3 or 4 more input jacks on the back. I guess so the whole band could plug in! I passed on it because of those mods and have been kicking myself ever since!

Notice on the bottom 2 photos from that link above - the shafts from the top mounted knobs extend through the bell cover on the speaker to the pots in the lower chassis!
Fender's Bassman of the same period had an upper panel with the pots connected by wiring to the main chassis on the bottom. Fender's bottom chassis already had components with tagboard and rivet construction, looking more like their '60s offerings when compared to the other tweeds with "vertical" chassies.

GuitarZ: They say you should be on the same page about kids before you get married. I really think you ought to talk about expectations on outdoor Christmas/Holiday lights. That could have been a game changer.
