For sale a pair of Raytheon 5755 tubes and 12AX7 adaptors that are a well known upgrade for Jolida FX DACs. These were bought on eBay recently (link below). I originally bought some from a seller in the USA but when it looked like that first pair were lost in the mail, I bought these. The ones from the US then arrived so these are surplus to requirements.

Text from the original advert:

For sale are 5/80 made pairs of Raytheon 5755 a substitute different pinout for 12AX7. These Raytheon’s NOS USA stock are matched for gain and GM on the Amplitrex AT1000 at < 1% between triodes.

I've only plugged them into my Jolida to make sure they are working. They do and sound great, but should improve further with more use (I understand that 50 hours is the target).

Link to original advert:

Note - the adaptors sent are different to the ones in the advert. Not sure why, but the ones I was sent are nice a solid!

Cost me just under £50. Selling for £35 delivered.
