Item Condition: Used

Location: Perth (SOR)
Extra Info:

 

I bought two of these valve buffer boards hoping to make a valve buffer for my system.   Current pricing on eBay is USD25.64 (AUD 37.50) each - https://www.ebay.com/itm/6N3-2-5670-6H3-tube-preamplifier-assembled-board-Hifi-buffer-/281371898723

 

There's a good thread on diyaudio also on improving the board - https://www.diyaudio.com/forums/tubes-valves/238521-cheap-6n3-buffer-amp.html

 

When I powered one up it had some hum (on my oscilloscope) so I don't know if this was a valve thing, shielding, or power supply issue.  I had a valve headphone amp a while ago and it had hum that disappeared after a few days burn in, so perhaps it could be that.  Valves are a black art to me, so I'm not sure.  Unfortunately, I don't have time to research, so best to move them on.  I never put the boards into action, so I daresay it's simple for someone skilled in valves and has a spare voodoo doll.

 

Preference is given to a local person / pickup but I will ship at the buyers cost if there are no local takers after a few days.
