So yes, still more expensive than a set of the PV's but not outrageously so; and with this level of amplification the difference in price becomes even more negligible, relatively speaking.

 

i've never had someone with a BHSE tell me they had a problem with one of the stock Mullard re-issue (Russian) EL34s. if i shipped with PV tubes, it would probably be a disaster. I don't know how much profit would be enough for that to be something i would ever consider.

Given all the comments here about EL34 PH and other PV tubes, that sounds like a wise decision.  BTW I wanted to upgrade to the Shuguang Treasures if you are still doing that.  My email is in the stack there somewhere.

Purk, I believe your BHSE's current EL34 tubes are Holland-made XF3 (Sittard, Netherlands), not the British-made Mullard (Blackburn factory) XF3. Not sure whether yours may be the same XF3 design licensed from Mullard, perhaps with much of the tooling also from Mullard, but with a different base and getter. Both are excellent tubes, though there are likely to be some sonic differences that will come down to personal preference. This guy seems to love your Holland XF3's, in fact preferring them to the British Blackburns:

When I had speaker amps that ran EL34, I had some Blackburn XF2 and XF3; they were awesome but also quite warm sounding, and thus not a great match for systems that were already warm (that would not describe the typical BHSE/009 setup, btw).

Purk's tubes came from me, they are XF4s, which were made after XF1s and before the first run of XF2s, a very special tube and only bested in some ways by metal base tubes.

At least I think that is what he is still using, but I may be wrong?

 

Interesting XF history here, I have 6 sets of the earlier XF4s:

Ah yes, you're correct...and I believe Purk told me XF4 as well, but somehow my brain is scrambling small details more than usual as of late :(

The Holland-made brown-base double D-getter EL34 on that page are exactly what Purk's tubes look like.

I expect the PHs were never on the cards for Justin, since the quality issues were raised very early on - and we all know Justin's views on quality.

However, if Justin waits a while longer for a few more impressions of the MBs, and those impressions stay positive, then he really does need to give them a go, maybe as option for the next batch. IMO, they are so comfortably ahead of the Treasures and at less than half the price, that it's a no brainer.

 

However, Rico613, if you still want the Treasures anyway, you can have mine at a bargain price. They have been operationally faultless and they sound better than stock, but I've got no reason to keep them after having got used to the PHs and now MBs.

That looks sick :D.

I'd be worried about any coloration of the sound though ;).

May have missed it a while ago but what exactly is this MB tube people are discussing?

Mesa Boogie I believe.

For those thinking of trying the MBs, but didn't take notes from the posts from a couple of weeks back, then see the section about colour coding in my post #5487.

You don't get the option to choose the colour when ordering from most suppliers, so you have to tell them. It seems to matter, as Golfnutz reckoned his Blues were smoother than the Greys.

I've only got the Blues (!), but had I understood the grading before ordering, I'd probably have gone for the Whites.

That purple really pops. Not my choice of color, but it came out well for those who'd have it.

To me Purple BHSE doesn't look bad, but when it comes to audio equipment I'd alway's go for Silver.
