5F6A came with two, maybe slightly more different versions. V2 cathode bypass cap and tone stack are the differences. I’m trying both of the versions
found this nice and old datasheet probably was a part of the Jensen brochure. and it’s great to see the exact output of the 50’s Jensen speakers. P12R was the stock speaker for tweed deluxe. and now I can see why it came with tweed deluxe. btw, P12R and P12Q share the same bell cover. and you cannot install P12N and P12P with the bell in tweed deluxe because of the size.
P12R = 12watt
P12N = 18watt
and, this thread in the same forum says
P12Q = 14watt
P12P = 16watt
The next evolutionary step for humans. Some of us will make the conscious choice to have our bodies integrated into a machine such as a spacecraft or a probe. By integrated I mean encased in a pod permanently connected up tp a “Matrix-like” system where our bodily functions are taken care of by the pod and where the sensors of the ship become our senses and we are the mind and soul of the machine.
A perfect blend of machine and flesh.
Over time our bodies would mesh with the pod and we would look very little like a human. To human eyes we would seem grotesque and removal from life support would mean death, So, our bodies remain in a windowless pod greatly shielded from radiation, heat or the effect of gravity or g-forces.
Then as this hybrid being, we could survive where no human could survive. We could live indefinitely if we slowed the body down while keeping the brain functioning. We could explore the universe this way. We would be more than human.
Not sure what I’m going to do with this speaker while I don’t have any SF or BF fender. I remember my friends older than me loved it when I was a kid. even I still remember how the sound was. I saw the same speaker with gray and orange frames. this D120F came from 70’s silver face twin reverb and it’s orange. and it still has the original cone
found this nicely built 5F1 with 10″ WGS speaker in Mergili cabinet on Ebay while I was in search of the parts for my first 5F1 build. grabbed it off for very good price and I’m changing the components and wires one by one like the filter caps, bypass caps, speaker wires along with the plug.
I think the speaker wires and Amperex 12ax7 changed way more than the capacitors. I’m waiting for yellow and red Jupiter 0.022 caps as well. an A/B comparison video on youtube was very interesting. and red one looks very close to the original Astron firecracker.
there are few tweed amp inspired cabinets around. and it’s the first cab I like except for the original ones. this cabinet sings with WGS ceramic speaker. I’ve been biased toward vintage Jensen alnico speakers so far. and this speaker changed it a bit
the orange filter caps are Roederstein 33uf 450v which replaced the stock caps from the kit. I didn’t know the limit of 5y3 and was brave enough to put two of them on it. then realized the rectifier was too hot and went to 33+10+10.
the first 33uf right next to the rectifier seems fine so far. I’ve tried on the original 5D3 and 5F1 without an issue before. this very capacitor is one of the caps I trust most
this 5F1 is dead quiet and the filament wiring is a bit different to the original champ. I’m trying to figuring out it. nothing is easy with the electric stuff even 5F1 is this simple.
I’ve got some NOS Sprague black beauty caps 15 years ago and tried it on this amp. I expected something vintage with them. but I’ve learned they are not useful as the coupling caps. they were good as the guitar tone caps. but they dramatically reduced the output volume regardless of the values. realized why my 18watt replica’s output volume was that low 15 years ago today. I’m still wondering why anyway.
[update] the sprague caps I put on this amp had twice high capacitance than the marking. I couldn’t find any 0.02 and tried 0.03 but they actually were over 0.05. higher capacitance changes the frequency and reduces the output volume as I learned from them. and NOS caps need time to break in. they sound getting louder for the last few days
