Hey folks, I have an old AC4TV I'm monkeying around with. I've got a load of spare parts and I'm seeing what I can do as a "junk build." I really don't want to sink any money into the unit if I don't have to. The original speaker is garbage, but all I have to replace it right now is a moderately okay Jensen MOD 10. Trouble is, it's 4 Ohm. Now, I have a 4 ohm Champ-style transformer that should be just fine in this build, but the issue is the AC4TV's rotary switch attenuator. Here's the schematic. My question is this: if I switch to a 4 ohm speaker and 4 ohm OT, what changes do I have to make to the attenuator? Do I need to alter the resistor values? Do I need resistors that can handle higher wattage? (I believe the included resistors are 3 watt.) If you comprehend how this would work, your input is appreciated. Thanks!
