Schematics

		Schematics These schematics are from a library I have been compiling for years. Look for the ones marked 'TESTED'; they are plans I have personally built and tested. Only unique design and good performers are posted here. Enjoy!

	PUSH- PULL Amplifiers
		Differential E88CC input DC coupled to E88CC driver - PL509 output, SS rectification
		SV83 PP, 12AX7 input/phase splitter - SS rectification
		6J5 input, DC coupled to 6SN7 splitter with EL34 output
		12BY7A pentode input DC coupled to 6CG7 splitter
		EL84 output AC coupled to long tail ECC81 splitter - EL84 output
		12AX7 differential input - EL84 output - Tube rectifier
		EF86 tube input with ECC82 phase splitter - EL84 output - Very simple design
		EF86 differential input with solid state CCS source - SS regulation - EL34 output
		Power Supply for above Amplifier
		6SL7 xfmr coupled splitter - EL34 output SS rectification
		XFMR coupled 6550 amp - Tube rectification - EL34 driver and line amp, all xfmr coupled
		6SN7 input and phase splitter - Unique splitter design - Phase balance adjustment
		SRPP differential input using 12AX7s - Good design - 6V6 output
		Differential input 6DJ8 DC coupled to 6350 driver stage - 6CA7 output - SS regulation
		6C33-B output, xfmr coupled to 6BM8 driver - SS power supply - Good design, should perform well
		6SN7 input and phase splitter - Vintage high power design - 6146 output tubes
		6DJ8 differential input DC coupled to 6SN7 driver - 300B output - The input and driver stages were tested on the breadboard giving excellent bandwidth - Good design
