Heathkit SB-220 Linear Amplifier. This is an all complete unit with Original Heathkit Assembly Manual. Inside has 2 x 3-500Z tubes. Bought his a a recent hamfest and original owner said it was still working. Being so old I suggest having this unit gone through by a tech to make sure everything is good. I have not tested this or even power it up. Unit appears to be all stock and original. There is also a small little dent/ding on the top cover which is hardly noticeable in pictures above. But it is there in picture number 9. Please see all pictures. Thank You and Good Luck :.
