Exclamation Tubes vs. tranziostors

The tubes or tranzistors. Which are the best?
In my opinion the tubes rulz!!! The sound provided by THE TUBES is incomparably better then the sound provieded
by the tranzistors. I think if i'll put modern speakers on my radio, the modern? digital cosole will sound like a junk.
O.K. I wouldn't like to have a Personal Computer (P.C.) with tubes, 'couse it'll be bigger than all the flats from
the floor that I live.
But here are the adavntages and the dezavntages of tubes and semicundocturs (diodes, tranzistors, cips):
TUBES
Advantages:
- the background noice (side tone) is lower than in the case of tranzistors;
- if you don't find the proper tube taht you need, but you have one that haves almost the same charactertics with that of the
tube that you're looking for, you can operate the so called "base (cap) modifications";
- it's simplier to see if the apparatus (device) is not working because one of the tubes failed (in cae when you have mixed supply,
it's not so easy; you heave to check every tube);

Dezadvantages
- they work at high voltage, so the risc to get electrocuted ("fried") is bigger;
- they need heater voltage;
- they are heavier then semiconductors;
- they are more fragile;
- the incoming power (power conspumtion) is bigger than in the case of tranzistors;
- a tube apparatus (device) is more expensive than a tranzistor one

SEMICONUDCTORS
Advantages:
- they are lighter than tubes (so a tranzistor device will be lighter)
- the incoming power is lower than in the case of tubes, so a battery/accumulator will work longer
- they don't need heater voltage
- they are smaller (so an tranzistors device will be smaller)

Dizavantages
- there are many tipes of tranzistors (for ex., I think abou 70% procent of the radios on this world are using tube type
EL 84 = 6BQ5 = 6P14P = 6P15P)
- the'res also Germanium tranzistors and Silicum tranzistors'
- the background noice is bigger than at the tubes
- they are less rezistent at the atomic radiations


EXCUSE ME IF I MISTAKE SOME OF THE TERMS, BUT I LIVE IN ROMANIA; SO I DON'T SPEAK CURENTY ENGLISH

And one of the other dezavantages of tubes is that at the tubes or hybrid tv sets you sometimes need to adjust the image.
