I'm not specifically targeting your opinion, just stating mine. Everyone has personal experiences. Mine was the kind that left me shaking I was so pissed off after they hung up on me and refused to answer the phone when I called back, and I hadn't insulted them or yelled at all, they just didn't want to help me as a customer, and hung up on me.
I had just spent like 200$ or more on new matched pair of el34's and some 12AX7's for a vox AC100. One of the EL34 tubes, the moment I put it in, smoked resistors, and was shorted from pin 2 to 3 internally, putting B+ on my heater rail nuking all tubes heaters. I asked that they only replace the tubes I'd just bought from them, even though they destroyed two other EL34's and the remaining 12AX7's I had for that amp. They refused and said they'd ONLY replace the EL34 that had the short. They then proceeded to tell me that 400VDC on heaters wouldn't harm the other tubes and I'd made that up and didn't know what I was talking about, and when I tried to explain most tubes have max 50 to 100 VDC allowed, he hung up on me, and wouldn't answer the phone when I called back. Multiple emails to sales produced nothing either so I took it to social media, their FB page, twitter, etc, and they just deleted my posts. Someone finally contacted me saying I needed to stop being a jerk and they'd always promised me all tubes to be replaced and that I needed to stop lying.
This is why I'll never shop there again.
