Thanks joe cool 85 I,ve never been referred to as an oddity before LOL any thoughts of how to convert  it back to a battery amp please
Thanks

Hi Guys

QuoteThese amps were meant to be powered by 40 C cells, +60VDC.
The power supply was added later.
It *looks* like you have a side mounted male power sock, to which you plug a female 2 pin connector, is that so?
It also *looks* that the power switch handles DC (as in the battery one), and the transformer is always on.
I also don't see any "death cap", but it might be present in the power supply itself.
Neither do I see a fuse !!!!
The green and yellow seem to be soldered to the negative (ground?) lug at the power supply capacitor, but if they are ground, why does the yellow one go straight to the board, and the green one is switched?
I think you should open the black tape bundle and draw a schematic of the power supply wiring.
Take a picture there too.
This is *not* a conventional amplifier.

hi it is a female 2 pin connector,this is a picture un wrapped ,no fuse i can see,as to draw a schematic i dont know how sorry,Can I easily convert this back to batteries? as I would love a little portable amp
Many thanks

No idea when it was converted I have obviously been lucky not to electrocute myself (some would say a wasted chance to hasten my demise)
LOL

Hi Phil thanks I,m in the UK so I think we are still  in the grip of rationing LOL sorry that ended 50 years ago " I think" it's the cold climate that causes our apathy ,I did a wedding last month and the mechanical curtains seemed to draw so much current and yet move so slowly that at the moment of the bands long awaited  emergence something tripped (suppose that's a good thing) so we were revealed  un plugged ! the look of astonishment on the bass players face was wonderful with the drummer still in full flow (are drummers actually listening LOL) the manager re set and we were off but, later that night over a beer  he said "it always does that" and scratched his head, I should have said "why not fix it then!!!!!!!" but I,m British so we just we accept nothing runs on time, everything is expensive, a summer is something other countries have, The list goes on and on ,thanks for info I wont ask what the weather is  like where you are ,as we are presentably being continually lashed with rain , its cold and we have pending postal strikes!!

Whoever said the last time the went to France it was closed LOL had obviously not been to England

Thanks

Hi this amp stuff has me a little concerned I have been trawling the net and this excellent forum
Question:
Is it possible (advisable) to connect some kind of resister in my guitar at the jack socket to protect me if the amp or the power supply or PA should have a fault?
Or is Is there some device I can place between me and the supply as some of the gigs I do , they have so little regard for the temperature of the beer I,m sure the integrity of the wiring is dubious possibly lethal! (like the beer)

thanks

Ps I remember the lip tingling mic days and always put it down to poor shaving technique LOL   

Please see my first post


Sorry haven't quite got the hang of this posting yet I will endeavour to do better

Hi joecool85 Many thanks if I may impose on your knowledge again

Both of the wires going to the plug are black ,at my friends house he told me that the mains plug was in the wrong way round as it hummed louder ,when the guitar jack plug was in the input (but not connected to the guitar) but dangling in front of the speaker? And we put the plug back in rotating it  and it did reduce the hum considerably is this correct ? as he only remembers this from distant conversation over 20 years ago and
as the two wires going to the socket are both black?

many thanks

Hi Guys and girls just joined the forum I have had several vintage amps and I have a question?I recently moved house and came across my old Mike Matthews Freedom Amplifier it's the 10" non battery version plugged her  in and "unbelievable "it sounds as great as it did the day I bought it .It take a while vto power down but I think it always did? I took it to a friends and he loved the sound but was concerned it had a 2 pin power cable so it wasn't grounded? I know its an old amp and if I,m going to use now should I get it converted to a 3pin grounded plug? And can I do this myself I build acoustic guitars so I'm relatively practical,any help most welcombe
Many thanks
DG
PS Concerned about this switch of "death" that pervades the internet
