Hi Myles (visiting from Harmony Central)
I have a Boogie 50/50 power amp and would like to check with you that I'm using the correctly rated (?) valves. I'm currently using Harma STR 6L6GC valves (30 MA, 3.1M/AV) as supplied by Watford Valves. How would these compare to Mesa Boogie 'branded' valves. i.e. what colour rating would they equal.
The guy that serviced my amp set he could not change the bias of my power amp. Is this correct ?
I am asking all this as I only seem to go 5-6 months without a tube going bad. Would failing capacitors cause premature valve failure ?
Any help would be appreciated.
Thanks
Dave
