See also the new easy wire secondary P-T1650XA tube output series; Enclosed (shielded), 4 slot, above chassis Type 'X' mounting. I am using a modern Svetlana KT88 to show what is possible but other brands of KT88 or 6550 could be used similarly. 5K, 2K, 2. S. My DIY system, 7236 preamp and KT88 SE power amp. 300B/2A3/6B4G/ EL34/ KT88/ 6550/ KT90 etc. Key Features:. The right on the photo is the R core output transformer in bare condition.

My own design, similar to 6AQ5 amp above, but using 6V6GTs and 10 watt RCA 972623-12 output transformers. 00 KT88 single ended integrated amplifier, Output: 12watts +12watts at 8ohms, Frequency response: 15Hz- 40 kHz (+/- 1dB), Total distortion: 0. The transformers are hidden inside the raised section. 60. 5 K. In this design the problem has been solved through the usage of: an inter stage coupling transformer with a ratio of 1:1. A Power Follower project very short signal path and LL1660 transformer (June 2007). Output trannys contribute most of the distortion in a valve amp and have a limited bandwidth. 90 $44. Nov 12, 2016 · Parallel Ultralinear with Edcor XPWR033-120 Power Transformer, Edcor CXSE25-8-2. KT88 tubes are operated in Ultra Linear mode. and the price not contain three of tubes Audion Sterling KT88 Anniversary Parallel SE Mono Blocks. Hard wired point to point using better grade components and larger, hand-built Audion wound output transformers (EI96). Chosing A Replacement Output Transformer Now lets assume we have a set that has an output transformer with an open winding that must be replaced, and the output tube is a single 6F6. 00 postage. This varying load impedance is reflected back to the primary, so the tube, and output transformer must work into a varying impedance range. 1650P. This is a Kegger design, with adjustable feedback. Shop All Categories Guitar Amp. But the bass slam of all of our EL34 amplifier is 10 times better than average 300B Single Ended amplifiers (without feedback) The only advantage of the very best and expensive £4,000 plus 300B Single Ended is better midrange than our EL34. With no less than five sources signal inputs for selecting DIY Tube Bases Single Ended Tube Amp single ended 6l6/EL34/KT88 tube and the Lundahl LL 1664 Output Transformer Claus Byrith Cayin MT-35MK2 EL34 . The GXSE15-8-5K (15W ). 98 watts and that doesnt include the losses of the circuit and output transformer. Silver wire windings available at current market prices.
