[QUOTE="Mars, post: 340024, member: 817"] I am developing an EL84 type push-pull stereo amplifier kit for "first amp" builders. A popular magazine is attending a DIY workshop in August and this circuit will be built. Some ideas about the configuration of the amplifier has come up in discussions on the forum around split load phase splitters and 6U8 tubes. I am torn between doing a 6U8 voltage amplifier/phase inverter vs. a 12AT7(ECC81) voltage amplifier/phase inverter. Different versions of the Dynaco ST35 comes to mind. Keep in mind that this circuit is to be used for sources like iPods and laptops and does not need the gain of the Mullard 5-10 and other high gain amplifiers of the 1950's using the EF86 voltage amplifier and 12AX7 phase inverter. What do you all out there think? Have you built an EL84 PP amplifier as a first project or does this peak your interest as a possible future project? [/QUOTE]
