300B Tube Amplifier Build

The 300B tube can be the holy grail of every tube amplifier. Everyone praises for its sweet sound. Personally, I never compare directly between one amplifier to another amplifier using 300B tube, but I still believe the reputation of this 300B is not a false statement.

More specific, the single ended 300B design are well known for the best sounding amplifier compare with the push-pull. Single ended is also more economical approach since we only need a pair of 300B tubes. But it has the drawback, it is the low power output. It is about 6 watt per channel.

That is why in this 300B tube amplifier build, I will make this amplifier in single ended design with 6SN7 driver and 5AR4 rectifier to drive a headphone.

For headphone? Pretty disappointed?

I guess not. I hope the sweet sound of 300B can be heard more closely to my ears.

Fresh Catch, The Parasound DAC 1000

Sometimes we bought the vintage audio equipment's not because only for the built quality, or the sound signature, or the price. I bought this Parasound DAC 1000 because it looks just like new.

Parasound is the big name in 90's which at that time, I am just can saw it on the borrowed Stereophile magazine. So, when I saw this DAC today and sold to me for under $300, who can resist?!

IBASSO DX-90 Disassembly & The Capacitor Replacement

It has been a while I am not posting anything in this blog. This is because of my main job schedule is very tight, so I cannot even manage this blog at all. But thankfully I am still having my routine music listening session, probably a few hours a week, with the current audio setup is using the low cost AD1865NK DAC, the LM3875 Gainclone amplifier and SB-acoustic 2-way speaker system. For the digital player is iBasso DX-90 which I have used for very long time.

I am curious what is inside this tiny media player and I have an opportunity to open it up now.
