Gibt es im Bereich PLZ 64xxx 68xxx u.s.w. Mannheim Bürstadt Heppenheim, Bensheim, Worms ein #makerspace ? Ich hätte Lust, so etwas auf die Beine zu stellen. Wo man sich gemeinsam trifft, repariert, bastelt, programmiert, forscht, experimentiert.

Hier mal ein kleines Projekt im Quick ´n Dirrty Style 🤩
ein Kopfhörerverstärker in Röhrentechnik, ca. 2x 1 Watt Class A.
Das Besondere: es sind 12 Volt Röhren, wie sie früher in alten Autoradios verbaut wurden 🥰. Die komplette Schaltung ist Hand verdrahtet, ohne Platine, so wie früher, von Lötpunkt zu Lötpunkt.
Das Gehäuse ist ein altes Reststück Olivenholz, Grün gebeizt, Schellack Finish,der Deckel ist eine Schieferplatte.

Nun mein nächstes Projekt: 2 High End Monoblöcke bauen, mit je einer KT88 🥰🥰 und ECL86 Treiberstufe, Röhrengleichrichtung…. Bringt je 13 Watt Rein Class A. Stabilisiertes Netzteil mit 390 Volt, das sogar die langsamen Netzschwankungen ausgleicht. Hab alle Teile schon zusammen und die Platinen sind fertig. Nur noch aus feinem Olivenholz nen tolles Gehäuse bauen x2 …

….. hmmmm 🥰 ich liebe Röhrenverstärker 🥰. hier mein selbstgebauter, mit 2x5 Watt rein class A, EZ81 Röhrengleichrichtung, Magische Augen 👀, 2 hermetisch getrennte Kanäle, Stabilisierte Hochspannung, Röhrenheizung mit Softstart, Lautsprecher Schutzschaltung mit Einschaltverzögerung und vieles mehr…

Das Gehäuse stammt von einer Denon Endstufe. Als Lautsprecher habe ich 2 Schallwände mit Saba Greencones+Biegeschallwandler

So, would I recommend the first generation Schiit Lyr tube headphone amp/preamp? Hell no. In fact, I will compare it to Rice Krispies. It snaps, crackles and pops. The noise floor is close to the ceiling, at least with the ancient soviet tubes I have on hand here. But am I having fun with it? A resounding yes. But not as my main headphone amp, I have the far better Lyr 3 for that. It's now a preamp in my retrocomputing basement, and I have a very crackly little party going on all by myself, listening to a bit of contemporary, bassy pop music, as 50-somethings do when they're left to their own (numerous) devices. #audio #schiit #retrocomputing #tubeAmplifier
I took the tube amp I just bought to the amp shop for a checkup. Est 6 week turnaround, due to demand.
See you later, new friend!

Another amp question.
Fender 65 reissue super.
It looks like the output jack shorts to ground when nothing is plugged into it.
And the jacks are in parallel, so both short if nothing is plugged into the main.
What happens if you short out the speakers like that? Would it hurt the amp?

КТИΝОΣ tube preamp (ktinos). The circuit is the preamp of the Model-T 1st-gen amplifier including the phase inverter which is a crucial part of the original circuit and plays a significant role for gain, tone and presence control.

4 Outputs for power amps have been included, two for each output of the phase inverter (0 / 180). Each output has its own dedicated output level control.

The preamp is AC powered with either 230V or 120V, selectable through a switch on the back side.
