This morning the amplifier arrived. At first glance it looks in good condition, all the valves are in place, Philips and miniwatt, and except for an electrolytic (2x16 uf. C106-107 in the scheme) that I have seen burst, everything seems to be in order. I have seen a Philips BE662A radio from 1952 that has two 800 ohm speakers that I think could be used.
The amp

Great!
The BE662A is of 1956.
It hurts me that is wil be victimised for another project, but it is your choice of course.
It is a fine radio.
If you do not mind I place the photo's on a (small) Dutch forum.

Sorry, 1956, you're right René. The idea of the radio is to use only the speakers. I will adapt other speakers to the radio with an output transformer and I will make room for it. It is a good device

I finally built the cabinets for ng4000 but I have some distortion/saturation in 9710 woofer output. I made a 70 liters cabinet with bass reflex. Tweeter sound is perfect
Tweeter are both small boxes on the top and 9710 the biggest on the left on the floor
