6X4 to 6Z4 Tube Socket Adapter | Great Product!
by Paul
I received 2 of these adapters from the Tube Store today (super fast shipping and excellent packaging as usual).
These are VERY well made and work excellent. It is great to hear the improvement in sound I can have over the stock 6Z4 Chinese tubes.
These are a bit wide and they will sit on top of the socket mounting screws that are already present on your preamp.
I would recommend buying these if you want enjoy the improved sound of your preamplifier with the 6X4 rectifier tubes.
