Well, to summarize, there is a ton of digital logic circuitary in this amp. I'd say its pretty much digitial circuits with a few tubes thrown in a mix of solid state audio paths. So, you have very high voltage tube circuits running along side very sensitive digital logic circuits. The chances of thi...

Thanks for the suggestion. Canada is a country the size of a continent. Even though it will show 20 locations, there is only one location in my city. Nevertheless, I took it to that location in my city. They took 4 weeks to diagnose and told me a whole long list of mumbo jumbo stuff that was apparen...

Blackstar/Korg has service centers worldwide.

With World wide, I am guessing you mean Chicago which is around 5 hrs flight from where I am in Canada and costs a few hundred bucks to ship there.

Update: So after 6 months later and going through various amp tech's, here is what i have learned; - Blackstar HT series are pretty much digital amps with a few tubes thrown in. The amount of Surface mount digital circuitry inside makes them look almost like a Line 6 digital amp. There are PIC micro...

These are pretty much digital amps with a few tubes thrown in. Miy HT-20 died after working for a few months with the digital circuit failing and I have not found anyone to repair it since then. If you want to throw your money at an expensive future paper weight, then go for it.

Did you ever find out what was wrong with it?

The standby switch is a soft digital circuit inside. Mine went into a stuck mute mode and has not recovered since then. So my HT-20 is now completely dead. The repair of a SMD digital logic circuit is very hard and can cost anything from $500 onwards, that is if a repair person will even take on tha...

This whole "soft standby" is infact a huge problem on its own. My HT-20 went into standby and no matter what i try, has not come out of that stage. No response from Blackstar on the issue. Think i will have to open the amp up and bypass the entire soft standby circuit, hopefully without destroying t...

Still waiting to get response to my messages and emails about my HT-20 that suddenly died on me. My first and last experience with this company. Will definitely stick to real Pro companies in future as i have done in the past.

I haven't had much response from Blackstar either. No reply from the Support. They do suck for Customer service.
