2013年12月17日 · The mighty KT88 is a lesser known tube to some that falls somewhere in between an EL34 and a 6550. The cool thing about it is that it is easily interchangeable with most 6550 amplifiers and can be interchanged in most EL34 based amplifiers with quick, easy mods.

2020年10月6日 · A very musical reaction, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very natural tone, make the TAD KT88-STR our favorite tube in the KT88 and 6550A class.

2010年7月6日 · to me, the KT88's seem bigger, and bolder, and clearer in their tone, whereas the 6550's seem to be a little more muffled, perhaps less mids, but have a little more grind to them.

The KT88 fits a standard eight-pin octal socket and has similar pinout and applications as the 6L6 and EL34. Specifically designed for audio amplification, the KT88 has higher plate power and voltage ratings than the American 6550.

2024年9月4日 · I'm looking for some sonic comparisons between these much-used octal outputs wired in triode. Plus any fairly close octal equivalents like KT66, KT77, KT120, KT150 etc. Not including the lower power octals like the 6V6 family which we know to be good - just those with dissipation of 18W or over in triode.

2007年3月8日 · kt77 has different tone and about the same output as el34 about 50watts a pair. kt88/6550 is a different animal, look for a little over 80 watts a pair. aside from the tonal differences between tube models (and individual tubes, really), you get more clean headroom when using kt88/6550's. so, if you like power amp saturation, don't go with them.

2007年11月1日 · the easiest way is to google 6550 tube specs and kt88 tube specs and compare them. tone is subjective because each brand / model has a different sound. both are great tubes if you buy the right brand. usually KT88 can handle a …

In terms of tone, the Electro-Harmonix KT88 has a very rounded sound. Its power handling is about standard, so it’s not the best option if you’re upgrading to get more volume. It’s an ideal drop-in replacement for British amps that use this style of tube, especially Marshalls, giving you the rich, vintage warmth of the original.

The KT88 vacuum tube is considered to be one of the best sounding power tubes for hifi tube amplifiers. In general, the KT88 tube has a magical mid-range similar to the smaller EL34 tube, but with low and high end extremes that reach much further.

2009年10月20日 · Can someone explain general sonic differences between the EL34, KT88, 300B, 2A3, 805, 845 in SET and PP configurations in terms of bass, midrange, highs, tonality, sound stage, dynamics, resolution, imaging, harmonics, etc. I'd be curious if there are references for the various output tube types?
