Hi,
First: Im biased, im a EL34 guy!
As most people here also i needed a retube and got the KT77. I had my fair share of tubes failing before so i wanted to go with what Peter recommended. At first i really liked them. Characters of the KT77 in my amp: Punchy, more pressence, less presented mids but more the a 6L6, stiffer dynamic response. I also would call it a modern tone.
If your switching or thinking of doing so, i hope my experiance can be of help.
Why i needed to go back to EL34:
- Had them in the Herbert already 4 or 5 years
- I was used to the dynamic response and character of the EL34
- I didnt find my tone balanced: the KT77 being more low and high focused. I would notice the difference most when doing muted runs, the tone would be thin and dull.
These are my findings. I had the EL34BHT before and got them again. I know there is a chance they wont hold up long but its a risk im willing to take. The KT77 i will keep as the spair set.
For me the difference between these 2 types of power tubes is big. The things i disliked might be the things you like.
