I have a 1950s Stromberg Carlson PA integrated tube amp with a 2-6L6 push/pull
output. It is a three channel amp each with a Vol. control (1 meg). With the
three Vol. controls turned all the way down, a moderate signal will still pass
thru to the output on any channel. What is the cause of this? Also a signal put
into any channel will bleed thru to the other channels. There are no other
problems with the amp. Your technical help is certainly appreciated. Please
email at: Thanks
