No. Disconnected parts will caue even more troubles. Just like removing parts from your car's engine and trying to start it. 
As a standard procedure and general rule for any antique radio repairs, all defective parts should be replaced before any power-ups. Replace all leaky caps. Check all coils and transformers for continuity of windings, etc. Replace any out of tolerance resistors (+/-20% max of nominal value).
NOTE: This set should have the speaker connected when power is applied or power supply damage or damage to other circuits may result. The field coil missing from the circuit causes abnormal B+ rise.
