Integrated amp made by
the "Deutsche Philips".
Due to their very low
output impedance EL86 tubes allow very simple (and strange) circuits with
small output transformers.
This way Philips also
offered 800 Ohms speakers which could be connected without any use of an
Oh! We have a GZ34
rectifier in this amp. But this doesn't help as all other parts are of minor
quality - especially the OPTs.
Philips: Great tubes -
bad amps. Sorry, but it is sad but true: Lots of their EL36 and EL81 amps
are not worth to spend time on them.
