Immediately behind the Lasonic TRC-931 in popularity within the Lasonic line just may be the TRC-975 “Jumbo”. Equally as flashy and attractive as the TRC-931 but BIGGER and with dual standard chamber side-by-side cassette wells. Additionally, one feature that is far better in design it appears is the presence of button selectors instead of the knob/function selectors of the TRC-931’s which are very prone to failure. A plastic gear manufactured within those switches do not age well and tend to crumble rendering the boombox to become stuck in whatever mode it was at last use before failure.
