I started my modification and DIY of Hifi around 2007. The 1st DIY project is the simple CAT 5 speaker cable which is low risk.

Then around 2008 I started to DIY tube amp, 1st project is the single 2C51/5670 tube preamp, then 5687 common cathode as recommended in diyparadise ‘s website. Then I seems addicted to DIY and can’t stop. Below are some of the project I had done for myself and friends.

Tube preamp/buffer:

Tube had been used: 5687, 2C51(5670), 12AU7, 12AX7, 5814A and etc. Rectifier tested in tube and solid state. For tube rectifier 6X4, 5W4 is used.

a) Single tube common cathode (2C51, 5687, 12AX7)
b) SRPP: (2x5687, 2x12AU7 and 2x5814A)
c) Cascode (2x5687)
d) Cathode follower (2C51, 12AU7, 5687)
e) Clone Marantz M7

Tube integrated / power amp: (All use tube rectifier such as 5W4, 5U4GB, 5AZ4, 5Z3 and so on
)
1) 5687SRPP-1626SE (both cap coupling and direct couple).
2) 5687SRPP-1626PSE (both cap coupling and direct couple).
3) 12AX7-1626-1626
4) 5814A-1626-1626
5) 5814A-5687-300B
6) 5687SRPP-300B
7) 5687-1626-300B
8) 5814A-1626-300B
9) 6BC4-1626-300B

Comments from Ken:

Nice to hear from you SS Wong! It seems like you're having the same fever as me! I'm a fan of triodes and direct heated triodes. You've quite some interesting projects there as well.

I wonder if you'd be interested to get your project write up posted in the DIY tube amplifier section? I'm sure the readers of DIY-audio-guide.com would love to see the details.

Check out my comments on tubes here as well:

Keep up the good work and hope to hear from you too!

Dear Ken,

I like triode in SE mode, my project more on low cost triode. Since you like DIY SET, we shall meet up 1 day for sharing.
