Fisher 500C, Infinity RS4b and Pioneer CS-8B

[Alonso83]

Hello everyone,

So my dad is all into tubes, like many of you too and his current set up is the following:
Fisher 500C, Infinity RS4b and Pioneer CS-8B

Can anyone point out to a few amps (preferably vintage stuff, but not necessary) that he could use to drive those Infinity and Pioneers? I know the possibilities are endless and if it becomes too difficult, could someone at least point me out to what should I look for in order to drive them? monoblocks? single amp? I'm lost..

Here is a video of the set up

These are the current specs
Fisher 500-C
Power output: 30 watts per channel into 8Ω (stereo)
Frequency response: 25Hz to 25kHz
Total harmonic distortion: 0.7%
Input sensitivity: 3.3mV (MM), 450mV (DIN), 230mV (line)
Signal to noise ratio: 80dB (line)
Channel separation: 50dB (line)

RS4b
38 Hz - 32 kHz !
4 - 8 Ohms
40 - 150 Watts rated

CS-8b
Not much info about these speakers other than they are 16ohms and I believe (could be wrong) 50 watts.

The Pioneer speakers should be a good match for the Fisher amp on the output transformer's 16 ohm tap. The Infinity speakers would require much more power and once you get into high power with tubes, it can get expensive. I would suggest at least the tubes 4 hifi ST120 or their M-125 if the budget allows.
