The heading of 'A Fresh One' is quite a subtle one :wink: :)

The head cab and chassis look correct for a 1965 amp (block logo, wide front chrome strip, white rear panel and single cut out for output selector 8, 16 and 100v line out so probably a PA originally).
There are oddities too.
The board is that of a '67 on amp (light brown perforated board, large disc Murata 250pF, 470k mixer resistors, added Lemco mixer cap, and is that a 100k on the bias diode feed? :shock: ). The plastic Torotor switches are 67 on type as well (mentioned in text - but they are much more difficult to get hold of than a metal toggle type.). The indicator is a later type than 65 too (but again an original type) as an original would typically have had a round RS lamp. My '65 is probably late on in 65 as it has script logo, thick strip but still RS lamp.

If it were a '65 then I would expect selector on the OT Drake or an RS type OT and a few other features. On my work pc I cannot get all the picture functions on ebay to work so cannot say more but I think the PT is a -118 again '67, must be failing if it only has 100k bias feed!!.

So in summary it is almost certainly a mongrel/hybrid/lashup of a '67 amp with '65 cosmetics (maybe original 65 box and chassis?) but I would not touch it with a bargepole at that price (mind you even if original I would not pay that). It would be worth a few hundred pounds or so as a parts donor :wink:

It sure does have all the hallmarks. I suspect the chassis is a modernfabrication. The box looks good though.

Warning sign #1 Seller using all that syrupy description.

Checked over by the best of the best in LA ! Yeah...... name them as most sellers do.

Those mustards always have a couple showing the date codes. This amp has one something showing but is not the clear style found back then. The 0.1 caps always have one showing B4N for example or likewise clearly readable.

A '65 with Red / White lead wires to pins 3 of the power tube sockets, that's an EL-34 O/T. And not a KT-66 O/T with Red / Black wires as it should be for that era or an R/S O/T........ No EL-34 O/T were used in '65 ! ....... Late '66 onward.

Murata & Lemco - wrong.

No voltage selector ? Should be on the MAINS Trannie...... fixed voltage ? on a UK amp with Bulgin power plug socket..... Nooooo

No Brown Hunts cap by the Fuse holder / mains power input socket.

Price ...... he's dreaming for that VERY questionable amp.

I accept wire transfer, cashiers check, or cash for payments. I won't accept Paypal. Not for something this valuable.

~I`m far from being an expert,but i`ve noticed all of that :wink: so it`s a hybrid a JTM 45 in an attempt, but at what cost :roll:
One question Gold block logo JTM 45 with full Iskra set ..plausible?
