The valve performed excellently in the ampegs, the classic growl with top end attack with either P. bass or Stingray was superb. The valves soundstage was larger than some other 6550 tested. The valve excelled in all the S.V.T set ups giving G.E type sound at a very competitive price. 6550A/STR HARMA 6550A-C TAD/RT886: Here is one of the new. The original 6550 tube was a pear shaped high power tetrode designed for power control by American Tung-Sol company. Later, GE and Philips produced straight bottle 6550s. The 6550 tube became quite popular in American audio amps in 1950s and 1960s due to its linearity and high power output. In later years, 6550 tubes were used in popular guitar amplifiers, notably in US versions of Marshalls.
I don't like the sound of the 6550 valve, so I have no direct experience as a long term user of such(and life of the valves will depend on amps used) but I would have said from experience with other types of power valves, that you are not getting as long out of these as I would have thought, this is assuming that the amp is working to spec 6V6 6L6 7591 KT66 were and are lower power octal based power valves that pre-date the 6CA7, KT88 and 6550. Screen grid Another fine helix (spiral) wire is added and placed between the Grid and Anode. A power valve with an added screen grid next to the Anode can be described as a Tetrode or Pentode. The screen is always kept at a high +V 6550 can operate at 600VDC and a screen of 400VDC, and Plate dissipation of 35 watts. We need to say here, that the MO Valve company had already build an improved 6550, it was the KT66. In 1957 the M.O.V. of England striked back with the another improved tube, their famous K.T.88, later sold as G.E.C. KT88, The KT88 had higher ratings than the.

The 6550 is cleaner (if you keep the PI the same), wider bandwidth and has a slight scoped mid feel compared to the EL34. Life expectancy of valves seems to depend more on the brand and the amplifier rather than the valve type. In my 14 years of owning,. 6550 The beam tetrode 6550, the standard tube in the Marshall AFD100, is similar to the 6L6 and came to life in 1955. Simply put, the 6550 can be used to create an amp that has a bit more power than with either the 6L6 or EL34. Tonally, it's in the same vain as the 6L6: clean, little distortion and an almost 'glassy' feel Electro Harmonix 6550 - Valves - Icon Audio Pentode Powe Vacuum Tube - 6550A, Valve Art.

The KT88 audio tube is considered to be one of the best sounding power tubes for hifi tube audio 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.The KT88 was invented by Marconi-Osram Valve Co. and became quick competition for the USA made 6550 tube Valve Art tubes are made in China by the O&J company. Their products are twice tested, and selected electrically and optically. Just the way you expect it. For the selection you pay a small premium, but for that you get what you expect, without having to say it. Available types are 300B, 2A3, 6550, EL34, 5U4G, and many, many more.

A 6N1P dual triode is used to drive the output stage Thanks, if I am reading the valve ratings correctly, the EL34 would considered the weaker of the two. The DA30 comes with either 6550's or KT88 (6550/KT88/KT90), but I would be interested to hear the EL34 to see if there is a different characteristic to the KT88. So this might be considered a step down in some regards valve module is never required to fully close. Typically, another valve is used in conjunction with the flow control-ler to stop the liquid flow. The batch controller type is for appli- cations requiring flow rate control where the integral valve module will fully close between batch dispense cycles. If total volume needs to b
So the 6550 and KT88 are not equivalent valves. There is always a suspicion with Sovtek valves that the 6550 and KT88 are the same valve in a different package; as there are no datasheets for these valves you can't tell. However the winged-C and JJ-KT88s have the expected parameters for a KT88 Fisher 6350 or 6360 Series pilots are used with one of several different main valves in pressure reducing, pressure relief, or backpressure applications. All of these pilots can be used in gas service, all except the Type 6351 pilot can be used in liquid service 6550 is also a high gm tube and has more power capability so 200 Ohms would suit it as well. It simply is'nt pratical to have one value (of cathode bias resistor) fits all but if you must try this then you need to use the 6L6 value as the limiting value My old mate and I were talking and he said he paid over 160 bucks for a quad of 6550's.
