Hi there. If I am on the right page I was wondering what everyone thinks the best power tubes and preamp (PI) tube they have have tried in their JMD1 ?

JCM 800 output transformer works on JMD's. Its upright configuration is a direct bolt-on on the JMD chassis. It will give your JMD a lot more balls... more punch with sweet harmonics. In addition a much needed 4 Ohm output is great bonus as well. I also installed a 3Hy 250mA choke. My JMD:501 sounds...
