Hi easternize

Congrats on your ownership of a truly awesome preamp!

I switched to Amperex tubes in my AG3000. They added more bottom end and "weight" to the presentation. I think Gilbert uses them instead of the Sovteks now (may be wrong).

Forum member "bjh" owns (and loves) a BC3000 mk2 so mebbe he'll chime in or you can pm him.

A quick forum history search produced this link:

No doubt there is more info available in past threads.

Best of luck with your pre,

chris

Tubes for BC3000 (and FtTH)

Post by Bob Neill » Sun Dec 12, 2010 8:47 am

Amperex or Telfuken, but good ones are scarce and expensive.

I like JAN 6922 NOS (Phillips). These are readily available for around $15 US and sound very much like the Sovtek (which I believe is now out of production).

If you prefer new production tubes try Electro Harmonix, inexpensive and very good.

Other than the JAN 6922 I tend to steer clear of NOS and older tubes in general since my experimentation has lead me to find that they are generally colored in one way or another (hence the wide variety of sonic descriptions).

YMMV of course but to my mind a good neutral perfromer in a BC3000-II is desirable since a "colored" tube would likely hold it back from full potential in one way or another.

Just to be the Devil's Advocate ... Bob like to "smooch" his sound (to get everything as close to sounding like AN UK as possible), and Chris has a preamp that actually benefits from being "tamed" somewhat, so look at what they say with tinted lens! :P :D :D :P

Getting BC to sound more like AN

Post by Bob Neill » Tue Dec 14, 2010 9:48 am

Au contraire. The BC sound is superb. But there's no harm is replacing dull, generic glass with something that has a bit more soulfulness.

If you ask me, YES. There are many would tell you otherwise but if you blow ooooooop you ampy, they are not the one who fix it for you. :) 8) You just have to be very careful of those tube sellers.

I have experienced tube sellers who will tell you this tube is the same as that tube. Turn out the filament current requirement is higher on the tube they are trying to sell. The result is overloaded the filament supply circuit and blow up the equipment.

Sometime tube has different rating of B+. Put a lower B+ rating into a high B+ rail can kill the tube. I just want to make if you want to buy tube other than the exact match, those are the couple of many parameters that has to match before the tube goes into the tube socket.

I have never really tried rolling tubes on my amps ... I am scared about doing damage to them. Am I really missing anything?

I have been getting my tubes from the TubeStore and have never had any issues. I change the tubes every 6 months, regardless if they need them or not.
