I have a 1960 Tweed Harvard but it looks like the output transformer was changed. The OT does have cloth wires so I assume it is from the 60's. the numbers on the transformer are:<br /> <br /> 022913<br /> E1A606 -- 428<br /> Can anyone shed some light on this for me. Thank You<br />

1964...Harvards, however, were produced '56-'61 I believe. <br /> <br /> w

Thanks Willie, I assumed this was a 1964 OT but do you have an idea what fender amp this OT was used for in 64?<br />

One has to wonder if somehow you have a very, very rare and very late model 6G10 which was produce n incredibly small numbers up to 1963 though, with Fender I've learned there are exceptions to almost everything we know as "true" and "fact"....what do the other transformers date at? Other features of the amp...speaker code, size, tube complement? Has me curious now...<br /> <br /> Otherwise, you could have a champ or princeton OT in there....<br /> <br /> w

Hi Willie,<br /> <br /> I have attached a link to photbucket:<br /> <br /> http://s1376.photobucket.com/user/tomyze1/library/Fender%20Harvard<br /> <br /> The speaker code dates to 1960 220006 <br /> The serial number is H02979 on the control pannel.<br /> I cannot read the two letter date code on the inside label.<br /> <br /> The amp seems to all original down to the handle. I have had it for over 15 years and it sounds great. When my amp tech looked at it a while back he said he pretty sure the OT was not original. There are a lot of much more knowledgeable amp people on this forum than me .

Oh yeah, that is an 5F10 ('55-'61) for sure....excellent photos. Most likely that is a '64 Princeton OT. Excellent amp you have there...keep it safe. :)<br /> <br /> w

Just now found this thread, sorry for the delay. <br /> <br /> The '022913' marking in your initial post is the part number, and is equivalent to the 125A10B OT used in the Princeton Reverb. But I doubt it's from 1964 as Schumacher did not change to the 022xxx part number codes until late 1965-early 1966. It should be a good match for your amp, though.

I have a '56. The output transformer was bad when I got it. Maybe it's not that uncommon... If it sounds good, then you're in good shape :)<br /> <br /> Dave
