did a simple job for a friend. he has some extra 50’s Jensen speakers and wanted to use them with this GT40 amp.
he told me GT40 has mono and stereo output mode. so, we decided to leave one of the 6.5″ speakers as it was. then put a long thread 1/4 jack on the other output.
the only place I found for the internal/external switch was the inside of the bass reflex vent on the back. the back panel itself is too thick to attach the switch.

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

[EDIT]
I’m updating this post not to make people confused. I believed B+ was lower with 5v4g than 5y3. but 5v4g is increasing B+ and makes the bias warmer than 5y3. I guess it is the reason I feel the amps are more alive with 5v4g
then I noticed the vintage amps with the original caps from 50’s and early 60’s are more vulnerable with 5v4g to 60hz hum. I’m just guessing leakage of the coupling caps and the filter caps could be the reason. I’m still enjoying 5v4g with the amps with new components. didn’t have an issue with my 5D3 which has new filter caps either.
[EDIT again]
one of my 5V4G tubes shows very low B+. the 60hz hum came from it I believe
there are more and better info for 5vg and 5y3 rectifiers on the gearpage.net
I hook up tweed champ, deluxe, and m-track 2×2 together while jamming with youtube. 5v4g sounds still alive with this stereo and digital setup to me. but, m-track 2×2 is cheap and sharing the one single full bandwidth with usb and instrument at the same time. it sounds good while using only one of them. it sucks when the knob is at the center.
it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers while playing guitar through the direct input. maybe I’m just doing this wrong.

all the black plastic parts have changed with vintage correct white ones. this Joe Bonamassa burst #70 has beautiful top and dark back with ’59 profile neck and Burstbucker #2 and #3. the orignal 50’s burst Les Paul guitars mostly had 7.5k to 8.4k pickups and many of them had hotter ones on the neck position.
Gibon’s burstbucker was made after the original PAF pickups which had unbalanced bobbins. I’d put #3 on the neck and #2 on the bridge. personally the best PAF replica was Timbucker from Tim white I got at 2003 with my Brazilian freboard 59 historic. and, at the time a few friends on Lespaulforum.com tried Seymour Duncan Custmop Shop PAF replicas and it was a great pleasure to listen them.
The same Duncan Custom shop PAF pickups are coming for this Les paul. and I believe he’d love them over burstbucker pickups
more vintage correct parts like truss rod cover and square jack plate are coming as well.

“He who fights too long against dragons becomes a dragon himself; and if you gaze too long into the abyss, the abyss will gaze into you.”
~ Friedrich Nietzsche
The German Philosopher Friedrich Nietzsche died in 1897 of brain cancer in the home of his mother. He had a nervous collapse in 1887 at the age of 44 and spend his last ten years totally and completely insane. He saw too far.
The American writer Ernest Hemingway killed himself in July of 1962. He had been suffering from severe depression and was undergoing electroshock therapy. He wrote that he was depressed because he saw the “black emptiness of human existence”. He saw too far.
You see my friends there is a dark place in our psyche. An abyss. The most intelligent and far-sighted of us can see into it. It is a frightening place. Not peopled with monsters or ghosts but with emptiness. An emptiness so complete that it appears that there is no end to it and no escape.
Yet, this is an illusion. The dark place is something we create for ourselves. We stare into it and it takes our hope. It clouds our perception and crushes our spirit. Yet, it does not have the power to destroy us. We must do this on our own. If one leaps into the dark place and embraces it then we fall through to the other side. On the other side is perfect freedom. Death is not the answer. Life is the answer. We can live in freedom from fear by embracing our fear. The darkness cannot touch us ever again.
“It’s done by hurling yourself into the abyss, and discovering that it’s a feather bed. There’s no other way to do it.”
~ Terence McKenna

needed a longer AC cord for my 5D3 and tried E3462-C cord. this cord noticeably reduces noise even while it has more amps and computers share the same AC and audio source.
then I replaced all the AC cord with this for my tweed amps. the most dramatic change comes to ’59 5F1 which was quiet alone but it cannot be hooked up with AB box. even 60hz hum was loud when it shared the same AC power source without AB box. ground lift didn’t work either. it just shifted the noise frequency
this seller has the cable. but, only one of three was correct. two of them were E3462 without C. they are metal shielded and the noise was louder than 2 prong cord.
https://www.ebay.com/itm/Black-CPU-Power-Cord-Cable-SVT-E-3462-C-LL-30830/253801406241
found another seller had the correct cable. and finally all of my tweed amps are dead quiet at any circumstance with E3462-C. even there is no difference between the original and modern 5F1 with or without the center tab.
and this typical ac cord wasn’t that bad for 5D3 but there is a huge difference with 5F1. E3462-C is still way better for 5D3 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.
