I love the sound of the Mullard valves and in my valve comparison they came out on top at the time. I will be trying some more valves and will include them on that page.... just taken delivery of some brand new NOS Military specification ultra low noise 6N23P-EV triodes made by the Reflector Corporation, (Saratov) and they run for around £5 for a matched pair which certainly is as cheap as chips! They come in sealed boxes direct from the factory and each valve has its own data sheet written in Russian...... I'll give them a try later on and can only hope they sound as good as the Mullards (you never know!) they certainly look very well made and a little birdie in the know reckons they are very similar to the Sovtek valves...... off to roll them in now and will report back later.
The guy I used to buy the mullards from (Sean Redshaw of highendaudio.co.uk) can no longer source them and he now uses electro harmonix valves in his amps instead of the Mullards and he swears by them...... I've got a pair of them on their way to try so will also include them in the comparison.
Valves certainly do play a big part in the V2 and can influence the sound greatly..... the stock Jan Philips 6922 are "OK" but there are much better sounding valves out there, it's just a case of finding them..... fingers crossed hope these £5 a pair jobs will sound good.
