Hello,

I'm looking for an opinion about Woodside (ex-Radford) ISA 230 valve integrated amp?

Data available: integrated amplifier 25 watt in class A
Valves: two 12AX7, two 12AT7 and four EL34 (6L6GA)

My question is, if it's close to well known power amp Radford STA25 mark3, which uses different preamp section?
I intend to use one of those amps for Tannoy Turnberry. Which one will be better? STA3 with good preamp?
Thanks.
