    What headphones do u recommend? budget <$250 (Use for mp3 player as well as some home use)

    Thanks

     

    No experience with headphones, but for IEM I'm using the HJE500 now, clarity, bass, comfort and fit is good. Might lose out to ATHCK7 in terms of sound quality a bit but for the price of 75, you can't really complain :)

    Hi, it looks similar. Without the schematics, I am only able to guess. :)) Hmmm where in SLT did you see this? In the large shop in the corner beside the staircase to Rochor Road?

     

    Wa! I can't remember already, already been a month or two since I last went there. BTW, I found their SG distributor, they are at SLT too.

    Thanks for the heads up, looks like it's either we install one of these or wait for the amp to settle than. Say, you think this will work too? It's one of those made in Thailand DIY kits that can can be found at SLT basement,

    FK650: SPEAKER PROTECTOR (STEREO)

    Detail:

    • This speaker protector circuit is the circuit that can connect to OCL stereo amplifier since TR output is directly connected with speaker.

    • Whenever the circuit is deficient, direct current will damage the speaker.

    • Power supply : 12V.

    • PCB dimensions : 3.3†X 1.9â€

    Guys,

    Just a tip, if you are building this, please try to include a protection relay into the output. During the time the tube need to warm up, the amp can send DC current into the headphones, burning up the drivers.

     

    AMB sells a board for this OR you can just ensure your earphones are NEVER plugged in when turning on the SOHA. A delay of 10s is said to be sufficient for the tube to settle down.

     

    Regards.

     

    Thanks for the tip! Sorry, noob question, i'm pretty new to this but does this protection relay function the same way as a DC offset capacitors like in the Cmoy amp?

    Interested in the lvl2 set, any idea how much it will cost in the end? less or more than $SGD200 with shipping?

     

    Did a conversion without shipping and its as follow.

    119.85 USD = 182.024 SGD
