Default RTP3 Tube Preamp PCBs assembled


For sale a pair of RTP3 Tube Preamp (Vacuum State RTP3C tube preamp clone) built from a French Group buy design.

Both Boards coming FULLY ASSEMBLED using very good quality Beyschlag, resistors, ceramic tube sockets, Russian PETP capacitors, Output caps PIO Capacitors.K75-10 / 1uF 250V etc.

They come with all the needed parts already mounted, EXCEPT the needed matched FETs. There small sockets installed so you can matched your own FETs, or order them from a very recommended seller on Diyaudio forum.

The only thing missing to complete this great preamp are the tubes (10 x 6922 needed), the supply power transformers, the two volume steps attenuators, and the input connectors, mute and selector switch. Parts list, schematics, documentation will all be included with the boards.

Sold as a pair since each PCB is for one channel only.
This is the preamp section only of the RTP3.
It doesn't include any phono section.

The Board Diagrams and stuffing guide I will send by Email and all the information I have available.

See these threads for the details:

AudiyoFan.org :: Voir le sujet - Preamp Symetrique. Caavance !

This is a very sophisticated tube preamp, fully dual mono, fully balanced with FET current source bias and built-in HV shunt regulator.

The Board build from Allen Wrights Tube preamp cookbook

Take note that these PCB are impossible to find anymore.

A warning! This is not a beginner kit.
You need to know how to complete the preamp, interconnect and test everything, etc.

I won't be able to offer much support since I won't have the working boards with me to assist you over email.

And since I never completed the preamp, I don't have reference readings either. I tested all the supply sections of the board and they are ok.

The rest is just the preamp (FETs and tubes) and should be straight forward.

But beware that you need to know how tube circuit works, HV work, etc...

Asking 280 Euro (for the pair) + Paypal add 4 % + shipping from Finland or Germany.

Accept PayPal. This is your one and only chance to get a pair of these so...
Send me a personal email if interested.
