Hopefully not seeing one in a while is a good thing? I’ve heard ASL hurricanes and was impressed enough to take a gamble on this piece.Oh, it says on the front! I remember those from back in the day, I haven't seen one in a decade+
Thanks Paul, is it worth upgrading any of the bits (caps...).The EI 6BM8 is likely a very good tube, and in this preamp it has to be a series regulator, so it's not super audible.
It’s a little snug given the base size. Last one is the remote which I need to trouble shoot.Can you post some pics of what's going on inside?
The need to change out parts may be mitigated by circuit design, which can be teased out of build photos unless it's all built onto a big PC board. Then again, if it's all on a PC board, I'd tend to recommend leaving it alone.
Thanks Paul, I didn’t recognize the black Bennic caps but the Nichicon ones certainly made me smile.I would suggest not touching a single thing in there!
Thank you for sharing, I was planning on changing them out with Mundorfs but I think I will leave them in place for now.I rate those Bennic caps. They have a clean open sound. I have them in my phono stage and I'm loathe to change them.
Probably not worth the effort replacing? My apple device sounded better without the amp...That could also be Chinese output transformers from the 90s.
Thanks Paul, I’ll call this preamp good and start enjoying it. Need to burn in the tubes but I’m pretty impressed by the gain, it’s probably twice what the Freya is.You'd probably find that upgrades in that position would cost more than the preamp is worth and wouldn't fit inside the box!
