Hi,All,Attached are my new hybrid amplifier using vacuum tube and IC.The tubes are ECC88 and the IC is LM4766.I make it with two small Al cases.

Very nice!

I really like that design. How does it sound?

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.

Its an interesting subject which gets very boring when people argue about it

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?

Rgds,
Mike.

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

Hi Luck,

Congrats on the superb amp there!

Can you tell me more about the PCB's there in the picture, Im really interested to know more about you amp? Are they kits and where do they come from? Thanks.

Hi,Mike,
The PCBs are designed by me.There are 3 PCBs in total.They are

CB 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.

Hi Mike,
Just trying to answer your questions. No need to be like that about things. You seem to be touchy.

So, I'll only correct when I see misconceptions, how's that?

Thanks Luck. Very nice website. I wish I could read your language.

Most guitarists love the sound of valves.
Its due to the warm sound of the distortion they give.

I use a valve mixer for my disco and also for my guitar and it sounds great.

I would recommend visiting a guitar shop and have a listen to a semiconductor amp then listen to a valve amp. Teh valve amp wins every time.

Thanks Luck, I was just interested in general really.

I would like to hear what all the fuss is about.

Yes, because a guitar amp does not need to reproduce a recording as accurately as possible. It clearly belongs to the creative process, so most of the time has to be appealing rather than truthful.

So should a hybrid amplifier sound accurate or appealing? In other words, how much should it sound like a typical tube amp?

Well, here we go again towards the famous Niceness Knob© that makes the sound adjustable from typical solid state to typical tube according to everybody's own taste.
