I put this video clip together this week. I thought some of you may find it interesting. I built a 5F1 Champ and a 5F2A Princeton.
The biggest known difference between the 2 circuits is the tone bleed knob on the Princeton. The 5F1 Champ is in the standard smaller cab
with a stock sized 8`speaker. It has a Peavey 4 ohm. The 5F2A Princeton was modeled after the later years in the larger sized
cab. There was plenty of room for a bigger speaker, so I built it for a 10" size. It has a Weber 10A100 8 ohm in there with a
multi-tap OT. Both amps have switchable negative feedback installed. NFB is off on both amps during this recording. Both amps
set to 10 on volume.(knobs go to 12) Tone knob was to 50% on the Princeton. No pedals, no FX, no reverb nothing here, just
amps, guitars, & cords. I played and recorded with a USA Tele for rhythm. ES-339 for lead and slide. 6 tracks. Both recordings were done identical.
The only difference here are the amps.

I welcome your comments if you want to share your thoughts. I will say that I am surprised that the 5F1 sounds meatier than the 5F2A.
I assume it is due to the the 5F2A tone stack taking some gain out. I suppose it could also be the differences in the amp components, parts, transformers etc.
I would have thought the 10" speaker would have sounded fuller, but that's not the case here. The 8" 5F1 does sound better I think.
The 5F1 has a Classictone PT, and a 4ohm Heyboer OT. The 5F2A has a Heyboer PT and an Allen multitap 4/8 ohm OT.
Cheers! Keith
