A couple of my latest creations.

Very nice!

Very nice!

Thanks. Here are a couple more pictures of the preamp. The markings on the fascia are etched with the saline sulfate method. This etch didn't turn out quite perfect, I slightly overetched it, but it's good enough. The etchings on the poweramp turned out better. Still some practice needed to really master the method.

Adolf,

I would like teh volume knob to be more modern and minimalistic. The vintage one spoils the excellent design.

Can't do that. Chicken heads are my personal signature. For better or for worse. And I like their feel. But rest assured, you're not alone with your criticism.

Just finished my preamp :

It looks good. I advise you to turn off the fan. my opinion it gives vibration. it can adversely affect the sound. I do not think that without it will overheat

 

[azazello]

Awesome! But fan is not good decision....IMO

 

[lexx21]

If you use a low rpm dc fan with the mounts insulated with sorbethane, it should be fine.

 

[male42]

The end justifies the means. I do not think that there is a strong heat. tube modulator is not a radio station. the picture of retro lamps with low power consumption. and fan and lamp things are not compatible

Everybody's a critic ;-) I get their criticisms. I don't think though you are trying to fool anyone. It's a modern-day piece using vintage glass; it's your take.

I hope it sounds wonderful!

If You don't hear a difference with fans on or off, use them to make things cooler and last longer.

Cheers!

Who can say anything?
Who can establish styles?
These are our things. I like very much blue valves with fan behind.
You can ask something of your curiosity but not criticized any.

I do not know English. I use a translator .A he roughly translated. I do not critique suggests. . I just expressed my opinion ..u I had a negative experience with the fans.It was heard in acoustics. in this forum, you can express your opinion ?. and to take it or not is a personal matter. because you have democracy?I liked the design. I wrote about this in the message №6708. good luck

What tubes are you using? 27's and/or 56's? Nice looking preamp!
I didn't know they made a blue glass rectifier.

 

[AatV]

Arcturus 27's and 80's as rectifiers. All in all pretty standard.
Funny to see the different opinions.

 

[a95sonoma]

That is absolutely beautiful, great job.

Car audio amp

Completed this a couple of weeks ago. Took about two months building it in my spare time. Uses two KT88 tubes for 22W out. Sub chassis is 1/4" aluminum covered with 1/4" purple heart wood and topped off with 3/8" copper square stock. Sounds wonderful.

Just started assembling my m60 mono blocks, slowly working out what I need to finish them
