Plastic tape head holders Porta 1 Porta 2 Porta 07 Base, Head 5760644200

These are surprisingly common cause of failure and I cannot get enough of them

They have a spring in which breaks or breaks the plastic, its a common problem In all of the Tascam and Teac units, I do not yet have the Teac part number but will add later

I think its in the Porta 5 as well

I just cannot get these for love or money so only turn up rarely
