Sony TC-WR645S Cassette Deck Repairs

A well-featured machine even if it wasn’t Sony’s finest in terms of its construction quality. These make decent recordings, and are fine playback decks especially if you want the convenience of autoreverse.

Aiwa AD-F500 Cassette Deck Repair & Review

My experience working on the AD-WX727 and AD-wX929 twin decks, the latter returning for a second round left a bitter taste in my mouth.

It has proven itself to be competitive in its performance and good value on the used market for the right price.
