Hybrid Amplifier in Small cases

Hi,It's a funny thing to build a hybrid amplifier is small cases.
This model use two vacuum ECC88 as a SRPP preamp.One IC LM4766 as output stage.

Hi Luck ,

Nice work . Congratulations .
I did have the oportunity to service and to listen many hybrid
amps , most of them built by the former Counterpoint Company,
and all of them did sound very , very nice .
I think that yours sounds very nice too , mainly due to the simplicity.

IMHO , simplicity is the first goal ,if you want to get a good sound
in any Hi-Fi or DIYaudio project .

Off Topic :
The “ Gotan Project “ is a good “sound” , too . Did you know that
Gotan is an anagram of Tango that is the Argentina native rhythm ??

Hi Luck, greetings from Japan!

I bought two PCB's in ShenZhen, China. The PCB's are as follows:

1: 6N3-T tube based line amplifier
2: Tripath TA2024 based Class-D Power Amplifier

These two PCB's are shown in my Blog below(sorry in Japanese).

I am planning to build HYBRID AMPLIFIER to utilize above two PCB's.
I hope the amplifier outputs cool sound at low frequency by Class-D
and brilliant sonic at middle frequency by 6N3-T.
 
Nice work guys.
This is my latest project.

An externally hosted image should be here but it was not working when we last tested it.


This a hybrid class D amp. I used 2 x Hypex UCD180, bypassed the input opamp buffer with JJ E88CC gold ( balanced and matched) SRPP stage and used a Classic housing( not a small one) and Rcore transformer. 4 inputs and Alps potmeter.

And it sounds relaxed you can listen the hole day to it.
