Well, I fired it up! No smoke or fire yet! It sounds great...when it is working! The power keeps cutting in and out intermittently like the power tubes are going bad, yet the power tube status lights on the back of the amp are not indicating failure? The modules that came loaded in it work fine in my RM100 and my RM100 modules also cut out when placed in the RM50, so I don't think it is a problem with the modules. However, I can sometimes get the power to cut in and out by switching channels or by manipulating the controls on the modules. Kinda weird!
All of the chassis tubes were removed and placed in a seperate, well packed box prior to shipping. When I reinserted them, I did not touch the tubes with bare finger-I used a cloth rag to handle them. Is it possible that they may have been damaged or that I did not insert them all back in the same spot they came from? The bubble wrap they were packaged in was numbered "1-5", but I guess I could have accidentally mixed up the 12AX7s. Two of them were labelled "12AX7", while another was labelled "Phase Inverter". Does it matter where they go? Which is the correct position for the Inverter tube? Could it simply be a biasing problem?
Any advice would be greatly appreciated! I really want this to work out because I have been scoping out RM50s for a couple of years and this was the first one that came up in the right price range for me. I got it for $379 loaded with the KH-1 and 1086. I really cannot afford anything more at the momement.
