most tube tuners have far better performance on rejection of STRONG
out-of-band signals, than do 'most' SS tuners even the 70's 80's classics.Now this may seem arcane, but if you think about the RFI environment today - both outside residences and INSIDE residences. With all the (RF speed) switching power supplies, in TV's, PC's, VCR's, and cable/satellite/set-top boxes /and PVR's (magnetic disk recorders) you may begin to see why this just MIGHT be an issue.
Most tube RF front ends also have very high overload performance in-band as well, so that use of a really serious directional antenna - or array of several - will not be a problem on strong stations nearby, and you still get the small signal stations. ;-)!
Tube RF stages may approach SS for sensitivity, yes, but they are not usually as selective. So that - IME&O - unless you are driving a tube tuner with a truly directional antenna with gain (IE NOT a dipole) you are not getting the full sound quality it is capable of.
lastly if there are ANY good AM stations nearby many tube tuners have good sounding AM stages, but an external / noise rejecting 'tenna will be necessary. For interiopr use a tuned pointable loop is the go. Build, or buy a Crane / etc!!!!
A longish (random length!*) exterior wire and a riboon,fig8, coax down lead and a tuning cap* is the go / an external bigger LOOP
