Teac A-3300 A-2300 VU meter

Now a rare part from the early Teac A3300 reel to reel tape recorder I believe also the A2300 which was the same but had smaller
size reels

These are now coming back into fashion because of the warm sound and audio quality of these old units

They were used in earlier models there is no part number on them just TEAC and a 3 in the corner
