Thanks Modi sir for your guidance and teaching in the past 2 weeks, and especially in the final completion work and testing of my 300B.
Thanks must also go to William for his timely support.
The 2 days and 2 nights' hard works really pay off.
After just 8 hours of audition, my 300B already sounds very muscial with excellent tonal balance. The treble, mid-range and vocal responses are unbeatable with lots of muscial details. The bass response certainly outperform my expectation with its richness and lower ranage extension though the control is less authoritative than my original KT88 (P-P) amp.
