The EQ531T is a 3 bands tube equalizer plus High pass filter, built around a dual triode, adapted to the 500 series of API*.

The MP566-II is the new improved version of the MP566 with high grade transformers and a new variable high pass filter. It is a dual-triode vacuum tube circuit preamplifier based on a design that was used in several famous devices from the 60's, which has been adapted to the '500' format of API*.

This screwdriver has a recessed head at one end which prevents it from sliding off the trimmer potentiometer head you are adjusting. Very convenient when you are working inside your lunchbox.

This tool is useful to bend the leads of resistors, diodes or inductors to a specified width.
One bender will be automatically included with your first kit module order.
Only order if you want more than one.
