My attenuators collection.

Here is my attenuators collection:
Weber "Mega Dump" - 200w. Designed for 8 ohms, may be used with 4,16 ohm amps.
Dr.Z "Air Brake" - 100w. Users can use it with a 4, 8, or 16 ohm amps.
THD "Hot Plate" -100w and 8 ohm model.


My favourite attenuator is THD "Hot Plate". The simple circuit inside the Hot Plate.
Passive fan is powered by the signal of the amp and only turned on
by high attenuation level with larger wattage tube amp.


"Light bulbs" feature noise reduction which is subtle.
