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
