They were budget priced instruments but were well enough made and worked to spec.
One weakness(on the 301 anyway) was the input overload protection. This consisted of 2 back to back signal diodes connected directly across the input. Connect it to a source of over 1V that could supply a bit of oomph and the diodes went S/C.
On mine ISTR adding some series resistance and capacitance before the diodes.
