i think i use too much bold :/
it’s my tweed deluxe 5d3 with Astron cap paper sleeves with Sprague caps inside. TE-1207 for 25uf 25V. and, 16uf 475V for 16uf 450V. I’m still after one more Astron 16uf 450V cap or sleeve. but even dead astron caps are not cheap on ebay. I tried it but the ending price went way further than I expected.
this 5d3 is getting closer to the original shape with the restuff filter caps. the correct switchcraft 1/4 phone plug and 18awg Gaviitt cloth wire are coming to me as well.
this wide panel tweed deluxe 5d3 came to me with weber 12a125a speaker a few months ago. it was a very good combo and the price was fair with the new skin. but, I couldn’t stand the blue color of 12a125a. everything else was good to me and my friends.
I’ve tried a like new ’51 p12r without bell, re-coned ’53 p12r came out ’54 5C3, black ’61 p12n, and this ’51 p12q.
p12q is known as one of the original speakers for fender tweed deluxe. but didn’t have a chance to play with p12q before.
p12q breaks up early like p12r. it was my first question while I was searching this speaker. and the question has solved.
I was obsessed with vintage jensen speakers a while ago. especially with p12n. but it didn’t work well with 5d3 because of the breakup point. or the family and the neighbors.
then p12q came into my mind. the sound was great like p12n even at the lower volume. and breaks up early enough like p12r in my imaginary world before I actually got this speaker. and it came true. I love this setup and won’t change the speaker again.
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
I’ve tried a few long plate 12ax7 tubes like black plate RCA, one of the common Telefunken, gray plate Sylvania with copper grid posts, and this one. Telefunken sounds great with 5D3 but ain’t good with my original and recent 5F1 amps.
this Tung Sol sounds like Telefunken with a modern 5F1 has Heyboer HTS-12005 PT. this PT’s B+ is over 400V with usual 5y3gt tubes. and this 12ax7 sounds great with the original 5F1 to me. grabbed off Reverb.com for $24
