What determines how good your radio will sound is the quality of the speaker, the alignment of the tuning, the quality of your antenna, the condition of the volume control, and the state of the caps in the power supply and elsewhere. The quality of the tubes is one of the lower issues. Even tubes with weak emissions by testing can still be serviceable. Tube brand in an antique radio is not so important, as any tube can go bad after all these years. Having a good test tube with no gas, no microphonics and that sounds nice in your set is about the all you need. Generally speaking, antique radios are "low fidelity" meaning the range of frequencies coming from the speaker is alot more restricted than a quality audio system.
