Description

The pair of output transformers 5K to 4ohm and 8ohm is for triode's tube amplifier 300B.AD1.2A3.6B4G.GU50.KT88(triode).... The transformers are made on HiB Duble C-cores ). The devices are winded frame less . It is a very neat kind of winding which does not allow any inaccuracies. The transformer's output power is 30Watt at 30Hz Maximum DC+AC current through each half-winding is 200mA The primary coil resistance is 145 ohm. The transformers are checked in real PP tube amp . with GU50 The frequency responce of the REAL amp. GU50 (90mA DC current) is 6Hz- 39kHz -3dB The insulation material is Mylar,which allows to make High Frequency Transformers! Quality of insulation : is more then 20Gohm checked with a megger 2500V ,during 1 minute . The weight of each trans is 3.7 kG Overall Dimensions are about :105*105*110mm I send parcels worldwide ! BUT YOU SHOULD ask me about the price of shipping ,before bidding...the worldwide shipping depends on the country and MAY BE LESS! !!
