Description

The pair of output transformers 4.5K to 8ohm and 16ohm is for 300B.AD1.2A3.6B4G.GU50.KT88(triode).... tube amp. 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 transformers are 15Watt power on 30Hz The core air gap is chosen for DC current 90mA . The inductance is 35H The primary coil resistance is 173 ohm. The transformers are checked in real tube amp . with one GU50 The frequency responce of the REAL amp. GU50 (90mA DC current) is 7.5Hz- 44kHz -3dB (the secondary coil is grounded ). 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! !!
