Hi everyone. I've managed to become the owner of a Bandit Transtube 80w amp with some issues. It's the one with the Vintage / Classic / Warm toggle on the clean channel, and the Classic / Modern / Hi Gain toggle on the lead channel. Master section has Reverb and Boost pots only. On the back is a Simulated Direct Output with a level pot, the 25% / 50% / 100% toggle, Loose / Medium / Tight damping toggle etc. (I can't find a model number, so hopefully this info dials in the actual Bandit series clearly) The amp powers up fine, and when placed near an electrical circuit there is a hum from the speaker. That leads me to believe that both power and speaker work. When a lead is plugged into either of the hi / lo gain inputs, touching the lead tips makes no sound. When a cable is plugged into the return socket in the effects loop, touching the lead tips makes a noticeable increase in the buzz. So... 1 - Is this a common fault, something simple to fix? 2 - Is it worthwhile on a $300 second hand amp (market price)? 3 - Should I cut my losses (which were minimal), convert it to a 112 open back cabinet with the original Blue Marvel? 4 - Any other worthwhile outcome to be suggested by you good folk?
