Thank you very much, vintagekiki! That was awesome!

I fiddled around with Google almost 2 hrs and found only the schematics for the older HT-5 instead of my HT-5R Metal. But found this forum, too :-)
Does one know the differences in the schematics between the HT-5R and HT-5R Metal?

This is something I did before... I know the actual difference in sound of both amps. There also much yt videos about that.

I own a HT-5RH (MkII) which has (had) a failed preamp tube. Once the amp was open, I found some unused soldering pads. So I guessed about what they are for - maybe used by the metal version of the amp. Maybe it's possible to make a HT-5RH Metal from the standard one by replacing some parts and equip the empty pads, too. Therefore I was looking for a schematic of the HT-5RH Metal.

[frank78]

If I'm thinking right, there could be a possibility to contribute an addidional pcb (that fits into the amp) which let one switch between standard and metal ;-)

So ladies, snap some pics from your open HT-5 Metal amp!!!

If it does not represent any great effort upload some pics from your open HT-5RH (MkII) amp!!!

I sincerely fear asking a simple schematic question here and being browbeat to pulp by tons of vintagekiki data

[alexradium]

these amps are made to be disposable,i mean,if there is a problem the official service guys toss the board and sub a new one.

Can't speak to current Blackstar policy, but most companies have a "do not repair" list. It doesn't mean the amp can't be repaired. And I have never had a company send me a board to swap. Amps on those lists are swapped out whole, not some board swap. The companies do not want to pay any labor at all.

[frank78]

Ok guys... Thank you all very much for the more and the less helpful comments on my question. But it seems to be the thread is running off topic a bit. I never claimed that these fancy and bulk build Blackstar amps are comparable with proven and expensive vintage(*kiki*) amps which are really worth it to put a screwdriver on for repair.

As a person interested in music and electronics I thought somebody could have the HT-5 Metal schems slumbering in a folder. Just for figuring out the differences between both amps.

Nevermind - I'll just put some ECC83 in front of the amp. :-)
Does anybody have schems for the Rocktron Gainiac 2?? Haha - just kidding!

If somebody has to change the tubes of his HT-5 Metal by coincidence, he could take some photos and post here. That would be very fine! ;-)

Trying to upload HT5-Metal PCB Pics

Hi Frank,
I am in the process of replacing the tube set in my HT5-Metal head and I have begun the arduous journey of finding out how to bias an amplifier. Well having some skills I am not afraid to do it, I just need the EXACT points to connect the meter leads to allow a correct and "smoke free" bias to occur. I have taken some photos of the PCB and overall inside of the chassis but having difficulty uploading them here? It wants a URL and these are from my phone.
