Attempting to produce a valve amp down to mid-fi prices, is doomed to fail

Not exactly true - attempting to produce a valve amp with mediocre componants
will result in a less than great sound, but not all audiophile componants are
expensive. Mains trannies - isolation toroids/low voltage toroids (cheap, RS
etc)
PSU chokes - Maplins 10H 100mA £7
PSU Caps/cathode bypasses - motor run polypropylenes, e.g. LCR £5-10
Coupling caps - Russian teflons £2 ea bulk
Input valves 6J5G £10, 12B4 £5 (USA) or any of 6N30, 5687, ECC99, 6SN7 etc
Resistors - Holco 1W
Output valves for PP: 2a3 £15+ each Edicron, 6L6 bulk buy on ebay £3 ea etc etc
OPT Maplins 6.6K £30
Put that lot together and you have serious audiophile gear on a very low
budget.
I agree that if you want to sink money into Lundahl iron you will be writing
out big cheques, but you can get into the ballpark with well designed RC amps.
