Electronics Repair Questions? Ask an Electronics Technician
Research showed that the Head assy of a 3340 is compatible with the 3300. I will try to send some pictures of the Parts list and adjustment page.
Another place you can check for TEAC parts is www.oaktreevintage.com I hope those informations are helpful. Unfortunately there are not many places anymore carrying spare parts for Reel to Reel Tape decks. If I answered your question please provide me with a positive rating so I can close out the questions.
