20 Most Recent Randall RT Series RT100H 100W Tube Guitar Amp Head Questions & Answers

What could be an issue is if the cabinet is a 4 ohm cabinet and you plug it into the 8 ohm output. of the RT100 ... IT WILL BE LOUDER that way... for a LITTLE while... till the power tubes get gassy from overheating and the sound will GO AWAY. VERIFY the impedance of the cabinet and plug into the correct jack on the RT100. Every RT100 will do this... it is GROSS abuse of the amp if you plug 4 ohm speakers into the 8 ohm jack. Some of the power tubes may conduct so heavily when they get gassy that they will cause a hum before total failure. The tubes will first get red, then orange plates and that drives metal ions out of the plates, then they get a purple glow and eventually blow the fuse or something in the power supply.

I understand your pain - was googling for similar, and came across this post, 5 years prior. My SGC Nanyo Bass Collection has just started to play silly beggars with the pots, and a bridge fault. Nowhere online seemed to have any details of the wiring, as the problem is, as you say, the fact that all of the tone and volume pots are based on a printed circuit board. If theres a nick or short on the board, its a pig to replace, and I really wouldn't like to have to wire any pots onto it. I'm currently looking at the options of ripping out the old electrics and wiring it from scratch myself. If you're still after answers, good luck!

PS - noted that none of the previous replies are relevant to this - mostly going on about the amps or a Fender guitar??!
