Lieber Martin Danke für diese interessante Meldung. Ich schlage vor, dass wir die empfohlene Bestückung im Gerät eintragen. Kannst Du als ersten Schritt Roy Johnson fragen, dass er sie anlegt - und dann diese auf dem Modell eintragen? Danke. Hast Du Kontakt mit Roy? Er ist ein sehr geuter Kenner der GB-Röhren (und wahrscheinnlich noch viel mehr). Zudem arbetet er sehr gut überlegt und geplant. |

Dear Ernst, Martin, All valves are now entered - only two additions needed! I shall see what details I have for them all and update as far as possible. Kind regards, Roy |
