I have a Philips EL3505 transport and amplifier and I have a restored Philips EL3509 amplifier. Even though they are different models they are very close to each other, the 3509 doesn't have a mic preamplifier built in, whereas the 3505 does. The connectors are the same, but the issue is the 3509 is English face panel and built for 7.5 ips and 15 ips, whereas the 3505 is built for 15 and 30 ips.

I do not know if the 3509 is the same as the 3505 electronically on the transport as the 3505 has the meter circuit and such and possibly the built in bias oscillator, I am not sure however. Does anyone have any knowledge on connecting the 3509 to a 3505 transport?
