WebThe amp has no parasitic chokes, although mine was very stable at six metres when tuning it up and it didn't show any signs of self-oscillation. But I did fit some chokes myself just for peace of mind, using 47-Ohm carbon compound resistors (one in each anode) each with a two-turn coil around the resistor body. WebEven better: most filter inductors (chokes) are rated at plus/minus 20% of the nominal value as per manufacturer datasheets. In summary: ... At audio frequencies we can assume that the parasitic capacitance will be insignificant and discard it for practical purposes. The new equivalent circuit is an inductor with a resistor in series. hard rock cafe bear https://doontec.com

WebDescription This design from Linear Amp UK with high specification and rugged construction has features normally associated with expensive linears. However, this model is offered at a very realistic price and it will loaf along at the UK power limitation. The low cost power tubes mean that tube replacement will not break the bank. http://www.foxtango.org/amplifiers/FL%20Amplifier%20Evolution.htm

WebWhen the amplifier was first tested, a potent 190-Mc. parasitic appeared during operation as a linear amplifier. Its frequency remained unchanged regardless of the addition of parasitic chokes or traps in the normal positions in any and all element leads.
