hi ,
it came to me with a EL3503 recorder ,
is it going to be the same for you ?
what i ´ve seen about this recorder is that it´s one of the best philips recorder ever ,
only found 1 video about it ....

[roginator]

I got set finally !!! tomorrow tests!!!

[roginator]

My machine is marked as 3566/01!


anybody with any expirience with this box??

[joumik]

hi roginator ,
that´s exactly the same as mine !

i have found this
Philips EL-3503, Radiophonic Workshop in New purchases Forum

but not much more ...
a friend has taken it ,the preamp too , he´s having a look on it ,
he has all the time it will need , as i´m on tour for a while ,
but i´ll send here all the informations i´ll find (if i do ...) ,

the friend was very impressed with the guts .... !!!!

hi ,
the preamp and its recorder have gone to another doctor´s house ,
it will be repaired soon ,
i still haven´t found schematics ,
it didn´t seem to offend the new doctor

to be continued

[joumik]

[joumik]

thank you all you roginator

[jeremyglover]

hey! i have an old phillips tube amp from australia.
i started a link here:
phillips tube amp advice/repair
as was suggest, the power supply was the problem, my tech is replacing it and removing a few things that don't need to be there also.
this link may help with schematics:
Amplifiers with valves.
look forward to hearing how yours sounds, i'll report back when i get mine back into the studio.
cheers, jeremy

[joumik]

hi jeremy ,
thanks for the links !
mine only had 6 or 7 caps to be changed ,
(including all the ones on the PSU)
and some dust ,
i hope you´ll get yours without hum when it´s back ,
looking at the PSU seems logical ...

[roginator]

Found schematics!!!!!!!

ta taaaaaaaa ... now to learn it!!

[joumik]

yeaaah great !
thanks a lot lot lot ,
such a nice idea to post it here !

mine has a strange behavior :
no sound at all when i plug the OUTPUT ,
but when only the microphone is plugged in ,
VU 's reacting nicely .
as soon as i plug the Output ,
there's no sound and the VU completely stops reacting ...


so ,
thanks a lot for the schematics !!!!!!!!

i'll try to find out ...

You get no output because there is no tape recorder connected !!
This amplifier is part of a quite old portable Philips tape recorder unit, also having been available in a stereo set (yes: TWO of these amps were used then..).
The VU meter is showing the input signal.
