Yes The original selenium rectifier has a rather substantial forward voltage drop The design of the filters and the rest of the receiver take this into consideration When you replace it with a 1N4007 the forward voltage drop will be MUCH less Chances are good that you ll apply too much voltage to the filter caps and receiver
