I need more sensitive speakers!

[Andrew]

Got this up and running over the break, needs tweaking, currently I'm using 6C45 as drivers but I'm thinking of trying C3g in triode. Anyway, one thing I do now know is that I need more sensitive speakers, 89db just not loud enough...

That's a big phono stage Andrew

Yes, and I'm having to be very careful not to burn a whole in the better half's very expensive rug.....it runs a bit hot...6 power supplies for 8 watts of 300B. I have clearly lost the plot. And I don't mean the 300Bs, no bass problems at all, not with a 50H choke input PSU.

cheers,

There is a lot to be said for separate power supplies. It means more weight, more metal, more heat and costs more but it can show improvements.

How are you driving your 300bs?

into what speakers? why not follow NickG's lead?

I started using my WAD phono stage and WAD pre, for the first time in several months; sounds awful !!! hm. though no hum.

happy new year.

Hi Andrew,

At the mo' I've got 6C45 doing the job driven into interstages, this is running at about 240v and 20mA, which is way off optimal, I think, but I ended up with more B+ on the driver supply than I had anticipated. I'm scheming on where to go next experimenting with drivers stages is going to be fun. The 300B's I have are knackerd as well so I need some new ones. I'd like to try PT15s but I need to sort the speakers as well, and the trafos are a bit too low for PT15. PCX have some 300Bs for $120 per pair (I think) the pricing is a bit unclear.

I really like the sound of the James/Nick OB but they won't fit in the room, several reasons including WAF. I need something with less width, taller is OK.

cheers,

Andrew,
you could try this guy for the 300bs, I've bought from him he's reliable,
