I bought two of these to replace the plugs on my 40 year old Quad 33 and 303 amplifiers. They are much more robust than the originals, which are of a different design with a right angled connection which saves space behind the amplifier. With a rubber strain relief sleeve, these protrude a good 60 mm behind the unit - not a problem for me. They are of an obsolete design and it was a great benefit to find them still on sale.
The bulgin line socket allowed me to make up a lead to be able reuse an old reverb unit as it was intended .
No cobbling in apiece of flex in , the flex went into the new pocket very easy .
Easy to construct and solder to the wire, not being a molded end means it can be opened and sealed easily. I used one to repair a.old 1978 synth and I'm happy with the result.
