this switchcraft black plastic plug looks always nice to me. especially with vintage Jensen speakers and tweed amps.
I recently noticed the material and the shape has changed through the years. I’m not sure with the exact timeline but, the first and second left ones look a bit older with the different shape of the end tips.
the first one on the left looks like the oldest brother. it’s the one for my 5D3 with P12Q now.
the next one came with 1953 tweed deluxe 5C3. the rest of them look like came from 60’s or 70’s production. I’m just guessing. I’m wondering when they started to put the nylon spacer not bakelite.
didn’t know Jensen had Concert series with ceramic magnets. this PM-1002 sounds more like Jensen 10J11 than WGS Veteran ceramic to me. even I believed it was an alnico speaker when I grabbed this off ebay for $69 plus shipping. then googled what Syntox-6 was after a week playing this in my 5F1 project. a bit disappointed while figuring out what the magnet was. but still happy with this NOS Jensen with the original box. and it is way louder than Jensen 10J11 alnico speaker as I expected.
I’ve tried Mullard and a few different 12ax7 tubes with it. and going to stick with GE black plate 5751 for a while.
didn’t expect any noticeable difference between them. but there are actually. Sennheiser 1/8″ to 1/4″ phone plug adapter sounds way better

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
The Supreme x Nike 2019 summer collection will be available at the skate label’s in-store locations in New York, Brooklyn, Los Angeles, London, Paris and also its online store from May 23. Japan will see a later release as usual on May 25.
purchased Adzam branded Heerlen 12ax7 and Brussels 6v6gt from from this ebay seller. they were NOS and the pricing was very good indeed.
he sent me this tube puller. this silicon tool designed to grab the preamp tubes and the the tubes like EL84. you still need to hold the tube using this puller. and it feels easy may protect the letters on the tube
