Tube preamp section + tube power section = tube amp. Silver Jubilee, some amps from Dumble, Friedman, H&K, Ceriatone, Mesa, and the list goes on and on and on and on..... are sold as "all tube" amps but have non-tube components in the preamp to get more gain, just like Blackstars.
No one grabs their pitchforks until Blackstar does the same thing.
This is a good example of the pedantic hypocrisy I talked about. Are you really saying that an amp that's had a Jose mod done is no longer a tube amp? Hey, whatever helps you sleep at night.......
Maybe you should talk to someone from Blackstar, like the guy who posted on this thread:
From the Blackstar engineer:
"Yes the Blackstar range, with the exception of the Artisan series, are hybrid designs"
Now, based on your past posts, my guess is that you are likely to read that thread and say something to the effect of "But look what he said about the DSL!!!"
Well, he didn't say what DSL he is referring to, so that doesn't help, but more importantly, he also doesn't mention what the ICs and ad FETs that he mentions do in the DSL. At least in a DSL50 ICs are used for the reverb driver and return, as is the case with many amps that people generally consider to be "all-tube." I don't know for sure what the FETs do, but it looks to me like they are used for switching; maybe someone with more knowledge than me -- which is a lot of people on here -- can verify that.
Note that this is not what's going on in most Blackstars. In those, ICs are in the main signal path of the preamp, amplifying the signal. They may not be being used to create distortion, but they are solid-state components amplifying the signal rather than tubes.
The Blackstar engineer also wrote:
"I do not think that you will find any Blackstar literature that refers to any amps other than the Artisan series as 'all valve.'"
He seems to want to get it right, and that's good. He must have not been aware that Blackstar actually was advertising the amps as "all-valve." They don't seem to do that anymore, which is also good.
Now, rather than anxiously await for you to call everyone hypocritical again, I'm thinking that maybe you're getting ready to mention a JCM900 at this point, so let's just deal with that in advance. Well, if Marshall marketed the JCM900 Dual Reverb today as an all-tube amp, I would be glad to call them on it, as would plenty of other people on here. We'd get our pitchforks on, brother! FWIW, plenty of people were very unhappy with Marshall putting ICs in the signal path on Dual Reverbs.
As for the idea that Friedman BE, etc. ought to be categorized exactly that same as a Blackstar in terms of whether the preamp is all-tube, Friedman doesn't hide the fact that there is a switchable diode-based clipping circuit. Guess what? When it's not on, the preamp doesn't use diodes. Try running your Blackstar with one of the ICs in the preamp removed. Also, it's not even clear that many of the other amps you're referring to were specifically marketted as "all-tube," anyway.
I owned a Blackstar amp, and liked it reasonably well. I have plenty of wonderfully solid-state pedals and a couple of solid-state amps. None of that changes the fact that an HT Club 40 does not have an all-tube amp preamp (or all-tube power section, for that matter). Carry on, though...
