johnyholiday Posted May 10, 2007 Share Posted May 10, 2007 Today old johny was sitting in the Flopp Pad ,on the phone staring right at the amp tubes, dealing with the office for a new AC unit {johny won} in the meanwhile the lawn crew had a big roll around blower with an old, Brigg an Stratton 5HP engine mounted on it ,coming along the exterior wall, of the interior wall that the amp is on, low an behold a EL34 {~200 hours of use} tube fizzled,and fuse........Theory: did the static off the B&S engine spark plug ignition system, take out the EL34 tube {ever seen a tube TV display, exhibit sparkles and lines,upon the passing of such an engine, johny has}?................PS it was time to put the tube amp in hibernation for the summer anyway ,Tubes in the winter,SS in the summer around here......"over an out on this crazy walkie talkie" Quote Link to comment Share on other sites More sharing options...

Guest " " Posted May 10, 2007 Share Posted May 10, 2007 geesh....more tube dynamic's.....now does this mean we unplug our tube equipment when operating the lawn mower or we need a cornwall vault type of enclosure with sound proof padding to place our tube equipment in during the operation of powered equipment?

Guest " " Posted May 10, 2007 Share Posted May 10, 2007 with 800 W/CH of dynamic power at 2 ohms, you mean poof, there goes my speaker cones flying across the street? 47 amps of current.....I think I can arc weld with that. Pioneer introduced the M-90 Reference Power Amplifier in 1987, to be used in conjunction with the C-90 Reference Control Amplifier. In the January 1987 issue of Stereo Review that ran the "Not Evolutionary-Revolutionary" advertisement, here is what Pioneer said about the M-90:"The M-90 is a superb high-power stereo amplifier, utilizing dual-mono construction. It is conservatively rated at 200 W/CH into 8 ohms and delivers 800 W/CH of dynamic power at 2 ohms. The wide dynamic range of the digital sources can now be reproduced effortlessly, with any loudspeakers. The M-90's high current capacity of 47 amps can handle the challenge of the most complex speaker loads. To further enhance S/N ratio and channel separation, relay-operated electronic switches and a long shaft volume control keep the length of signal paths down to a minimum. Why include a high quality volume control on a power amp? To pursue the straight wire-with-gain philosophy when using a CD player connected directly. Pure sound, redefined."The M-90 was virtually distortion-free, having only 0.003% THD from 20-20K Hz @ 8 ohms, and had a S/N ratio of 125 dB! (See the complete specifications at bottom of page.) The M.S.R.P. for the M-90 was $950.00. It was superceded by the M-91 in 1989. Quote Link to comment Share on other sites More sharing options...
