I started this build on my personal blogspot blog. then I moved whole the articles on slowbean. I might want to arrange them into one single thread later.

it’s my yokomo Hotdog4 built from YR4 kit with some Works bits, along with Yokomo Esprit stock motor. I’m working on the new shock towers. 

 

MX4 rear CVD bones fits perfect for ’91 through ’93 Works. Hotdog4 has the same arms. and you guys can see the result. the length is same with post ’94 yz10 rear cvd bones.

  • This post would be a help. but it seems impossible to get them unless you guys push MIP to make them again.

    Yokomo YZ10, Works, and 870C universal drives info

    it’s the basic info for Yokomo CVD bones
    ’94 YZ10 front CVD bone 84mm
    ’94 YZ10 rear CVD bone 79mm
    MX4 rear CVD bone 79mm

    Kysho RB5/RB6 70mm CVD bones work for 870C F/R

    MX4 rear bone works with ’94 YZ10 rear. and, Works F/R
    ’94 YZ10 rear bone works with Works F/R. and, for 870C front wide setup
    Bj4 front bone doesn’t work for Yokomo diff cups

    ’94 YZ10 front

     

    from the top, MX4 Rear / ’94 YZ10 Rear / Jconcpets BJ4 front.

    the length are identical to each other. but the head pins are not. I’ve tried more CVD bones from AE and Losi. and all the US brand CVD bones have bigger head pins which don’t fit Yokomo diff cups

    While the length is identical, Bj4 CVD bone don’t work for Yokomo diff cups

     

    ’94 yz10 cvd bones go deep inside of the diff

     

    MX4 bones have longer head pins. it’s fine except for 870C

  • en I’m into 5v4g than 5y3 with 6v6 tweed amps

  • [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 

    https://www.thegearpage.net/board/index.php?threads/swapping-rectifier-tubes-5ar4-vs-5r4-vs-5v4-vs-5y3.1382681/

     

    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.

  • 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 The next big IPO is just around the corner?

  • Beyond Meat is going public. Investors are betting on a new future for food. Plant-based meat products might fix our food system.

    Beyond Meat, the plant-based meat company, is going public next week. The company sells burgers that contain no meat, but taste like they do. Its stated goal is to fix our food system. Its initial public offering (IPO) is the latest sign that alt-meat is going mainstream – and that’s a big deal.

    It’s been a good few years for Beyond Meat. National chains including Del Taco, Carl’s Jr., and T.G.I. Friday’s have started carrying their products. They’ve also found their way onto grocery store shelves at Whole Foods, Kroger, and Target. In total, Beyond Meat says its products are available in more than 35,000 outlets, from hotels and college campuses to grocery stores and sports stadiums. Sales have been growing fast – last year the company reported revenues of $87.9 million, up from $32.6 million in 2017.
