Wow again some very nice designs have been posted! Hereby I would like to show my newest build; another LM1875 amplifier 🙂. Yes, of course it has VU's 😀! It looks a bit similar to one of my other LM1875 amplifiers that I have shown earlier, but the case is now a few cm larger in height. This allowed for bigger PSU capacitors (2x 10.000 uF). Despite of that it is still quite compact and 10 (H) x 10 (W) x 16 (D) cm in size.
VU-meter driver:
Amplifier board:
I am very statisfied with how it sounds. Every time it amazes me how good those LM1875's are. Although compact, there is no hum or any EM coupling to the circuit board. Those Amplimo toroids never dissapoint me 🙂
I've also made a little YouTube video of the amplifier in 'action':

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

Hello colleagues introduce you with its own system. In the video, push-pull hybrid amplifier. four-way system. Plus subbufer. https://www.youtube.com/watch?v=EjFsFoYntqA https://www.youtube.com/watch?v=YTDRk3v-nEE
Disassembling a Kalashnikov AK-12 could have been easier for them... But the inside of the Duet is beautiful...
Hi Federmann,
I loved the meters the first time you posted your pictures. Still love the meters and the overall look, but you only need post pictures once.
