Danke, noch habe ich nicht angefangen den Pre-Amp zu bauen, zuerst muss ich noch meinen Plattenspieler versogen: neue Zarge, Kabel, Abdeckung, etc. Gut Ding will Weile haben. Gruß aus der Pfalz

Issue? What kind of issue? That's an L-Amp!

Wow! An electric heater AND amp in one go! Nothing beats a multifunction device. And if you are a labyrinth enthusiast, you can use the schematic to build a modern version of the Minotaur's lair. Total genius, this.

Thank you, Moonfish. Sharing knowledge is always a good idea!

Thank you, will do. I thought as first steps I will try to comprehend the schematic, then assemble the circuit board without soldering and then measure the components to see if they are out of spec (or perhaps a bit "odd"), and if so get new ones to replace them … but the kit isn't yet with me so I'll just wait patiently.
