organ tube amps

Has anyone tried using these in a hifi audio system? If so, please let me know what you think.
for what its worth i see them on ebay alot, they seem to have a sizeable following.

LImited bandwidth on the output transformers I'd think. Overall, decent iron usually, but not plug and play. Not a bad chassis/platform to start with for DIY tube project, though. Webster seemed to make some of the better-regarded ones.

No top end, as organ harmonics topped out at around 4kHz (e.g., Hammond) so that's all the bandpass that was required.
Thank you all for responding.
