AC30 Vox owner ; tremolo / vibrato channel

[stratele52]

I have a Vox AC30 TB made in England 1996 .

Vibrato/ tremolo Channel are about 1/2 power at the speakers than the Normal / Brillant channel.  Is it normal ?   I don't know much about Vox amp. Tubes are good.

I fix a loud hum on Normal and Brillant channel which are now very powerful and working fine.

Thank's

I don't know about the normal channel but every AC30TB I have worked on or played the Brilliant channel was louder than the VIB/TREM channel .
