But what are the metal tags made from?

core made from copper surface gold plate

 

[Professor]

Very nice work , what kind of resistors are these green ones ? .

Thank you! This is noninductive wirewound resistors. PTMN (ПТМН)

Thanks for the answer .

But do you make them yourself? Do you buy them? Where do you get them?

(Who'd have thought it would be so hard for this question to cross the language barrier! )

Well.... In all fairness, your questions like "what are they made from" leave a lot up to interpretation. With many possible correct answers how is the recipient supposed to know which one of the correct answers you're looking for? Sometimes over-communication can be useful (as you did above).

@dberglez: cool tech looking!
What is the purpose of the hourglass? Heating up period?

On turn on, hourglass turned 180 degrees, turn the heating, and after 30 sec turn the HV. After 2 second, turn the other voltage ( input selector and Nixie). When work, every 60 seconds turned the hourglass to 180 degrees. I used a low voltage (190 V), and the amplifier is currently working in AB class and has a 7.6 W. I will install a transformer from 230V-240V (sec). If I'm right, power will be around 10W.

You are a man after my own heart. Great work. Very creative, stylish, well appointed, and well proportioned. I've been a sculpture for 41 years and I very much know when a piece is more than the sum of its parts.......You hit it dead nuts!!!

Thank you for your opinion. Nice to know I'm not the only who likes strange things. Thank you all.

My pp 6N13S finished today. More photos 6N13S - mymegahobby Jimdo-Page!

not sure if you bought it somewhere or just good hand working skill

Rusikie Aikido....6N30 and 6N23 logether in a single amp....

 

[stajo]

Cool AJT. Have a build/schema thread?

 

[TonyTecson]

this is just an implementation of Broskie's aikido....uses ac filament but dc biased....power supply is SS FWB with chokes and generous cap filtering, B+ rails at around 250volts....

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

I like this amp. Very small and clean, good work.

Well done!
The question under the scheme: not too high raised one of the heats?

 

[Triodethom]

Kathode to heater voltage should be less than 150 volts . 45 volts is what I would use. From the schematic it is 100+ volt to high at least.

My first tube amp project.
DIY enclosure without finishing...

6F12P front end and PP pentode connected EL34 power tubes.

Little testdrive...

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

and almost complete amp.

Sounds very good.

Looks sweet.....
Happy tunes....

 

[Airhead]

Nice work TurvenuijaFIN. You need only some transformer covers and some finishing touches on wooden side panels.

 

[dady]

Good morning Mr TurvenuijaFIN, My counsel, send the amplifier with some finish details to the Airhead's home, maybe also, he has some cans for the trannies.
