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.
Researchers at the Massachusetts Institute of Technology (MIT) and Harvard Medical School have teamed to develop a novel tattoo ink that can show your body’s health changes.
The novel ink consists of biosensors that react to changes in the tissue fluid and make the skin an “interactive display”. So far, researchers have investigated four biosensors that respond to three types of body information, changing their colors.
As the pH-value increases, the color changes from violet to pink, an increasing sodium content is seen as a bright green under UV light, and blue becomes brown when the glucose level increases.
This animation from a video of the researchers shows how such a tattoo might look like:
Especially for diabetics, a tattoo with ink that reacts to an altered glucose level could be useful. They have to prick their finger with a small needle if they want to measure their blood sugar level – usually several times a day. This procedure can be painful in the long run and can lead to small scars.

I see two of ACY41 germanium transistors on the board.
Grabbed this off ebay for a great price. two hundred something in USD. it sounds great and quite different than my Bum fuzz and old Sola Sound fuzz pedal a friend has.
but, it has an issue. it rattles on high level. I’m sending back this back to British Pedal Company.
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.
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.
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.
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.
They tweaked the large sprague caps and the small ones too much for the scene. but it’s still good to see my favorite sprague capacitors on a movie. aren’t they orange back in the days?

btw, I wanted to capture the scenes. and it didn’t work with Safari browser. this helped me out. you can capture the screenshot while it’s playing on chrome. it didn’t work while posed.
