Hi Mike,
You do know you are on a slippery slope here! Tubes are cool and fun to play with.

Its an interesting subject which gets very boring when people argue about it, which happens too much. I never heard a valve amp so I cant comment on the merits.

Hi Mike,
They all sound different.

Actually, it's discussion unless you have a number of people who don't know anything about the subject. Then it's a annoying waste of time. Once you have people who know the subject talking about it, everyone learns a lot.

Whatever, some like em, some dont. I cant comment as I never heard a tube amp or pre. I have a concept on how they might sound based on what I have read in past magazines and such, and I'm well aware they dont all sound the same.

Look, Im not expert. So I'll leve it there, ok?


PS: Nice amp Luck! I love it and I'd love to hear it, bet it sounds nice. :)

The PCBs are designed by me.There are 3 PCBs in total.They are:PCB for the Preamplifier using vacuum tube ECC88. The second is PCB for the power supply with high voltage and relay controll. The third PCB is for the LM4766 as power amplifier.
