  • en modern 5F1 with Boothill kit and Mergili cabinet

  • 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

  • en fender 1952 5B3 tweed deluxe restoration

  • it took a while to get the original Astron mimimite capacitors for re-stuff. came to 33uf + 22uf + 22uf and it turned out great with zero hum and Fender tweed deluxe voicing. it’s funny I met this amp a while back. a friend of mine had it. then another friend owns it now

     

     

    tried P12N and came back to the original smooth cone P12R after fixed the voice coil rub.

     

    it was like this when it came to me. the voltage dropping resistor fell off once I touched the soldering joint with my iron for 0.1 sec. a bit scary I could say.

  • en VHT standard 12 – a fat tweed deluxe 5e3 clone

  • it’s getting better with some NOS caps and tubes. 50’s Jensen does something of course. VHT standard 12 is a bit bigger than the original tweed deluxe. and I like this cabinet as well. I might try P15N at some point

  • en 50’s Jensen P12R and P12N output power – from tdpri.com

  • 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

  • en Sprague 16uf 475v fits perfect to Astron vintage paper sleeve

  • 5y3 rectifier tube in my 5F1 tweed champ went dead a month ago. and everything was fine after I put a new 5y3 tube.

    then, the same thing happened today. I figured out this 16uf 450V Astron minimite filter cap was the problem.

     

    Sprague 16uf 475v fits Astron Minimite 16uf 450V paper sleeve. my champ sounds firm and clear than ever with this new cap.

    You need to strip off the blue shrink cover to put it in the paper sleeve as you can see

     

     

     

     

    Sadly, I’ve lost 2 of these 5y3 tubes from this issue. but still good with the better sounding from this small tweed amp.

  • en NPN Germanium transistor list for Fuzz pedals

  • My interest in fuzz pedal came from JMI Tone Bender III reissue which belongs to a friend. this pedal has 3 of OC75 glass tube transistors.

    And, unfortunately, My Sola Sound Bum Fuzz came with 3 of NPN transistors while OC75 is PNP type. then found this web page with germanium and silicone transistor lists

    http://vintageradio.me.uk/info/radiocon_data_trans.htm

    There are 26 of germanium NPN transistors from the data sheets

    ASY28, ASY29

    2N388, 2N388A

    2N1302, 2N1304, 2N1306, 2N1308,

    OC139, OC140, OC141

    AD161

    AC187

    NKT713, NKT773, NKT774, NKT781

    2SD72

     
    Black glass tube NPN transistors are OC139, OC140, OC141 from them.

     
    OC75 is like this according to this web page on alltransistors.com

    Type Designator: OC75 (PNP)

    Maximum Collector Power Dissipation (Pc): 0.125 W

    Maximum Collector-Base Voltage |Vcb|: 20 V

    Maximum Collector-Emitter Voltage |Vce|: 20 V

    Maximum Emitter-Base Voltage |Veb|: 10 V

    Maximum Collector Current |Ic max|: 0.01 A

    Transition Frequency (ft): 0.1 MHz

    Collector Capacitance (Cc): 50 pF

    Forward Current Transfer Ratio (hFE), MIN: 55

    And, for OC139, OC140 is

    Vcb: 20 V / 20 V

    Vce: 20 V / 20V

    Forward Current Transfer Ratio (hFE), MIN: 40 / 75

     
    I’m going to try OC139. simply beccause, OC139 is cheaper than OC140 on ebay. and I’m wondering how Transition Frequency differences work with Fuzz. I’ll update in a few weeks

  • en Yokomo YR-4 special

  • there were more than one, at least two different YR-4 Special models I remember. this one is one of them. it came with carbon graphite top deck, shocks towers, and the chassis. the top deck was fragile and everyone knew it. at the same time everyone wanted to try it as well.

    this YR4 special is pretty much with stock parts except for Tech Racing shock mounting hardware which looks brilliant.

    I don’t have any plan for a racing track in a near future. but this white bulkhead caps brought a magical moment like the one I had yesterday. yeah it’s and addictive hobby. maybe all the hobbies are

  • en Fender Mustang GT40 amp external speaker mod

  • 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.

  • en Dine inside a pair of grasshopper-shaped locomotives at a South Korean cafe.


  • Grasshopper’s Dream is an insect-shaped cafe that sits along the popular Auraji rail bike route near Jeongseon, South Korea. The converted and stacked green train cars are placed near by the Gujeol-ri train station, and are each outfitted with protruding metal legs and thin antennae.
