Hi Guys,

I hope you can help me on this one. I have a pair of Philips PCC88 Tubes that came with a Little Dot MK iii headphone amp, but I can't quite match them to tubes that I've seen online?
Apart from being stamped 'Philips PCC88' the only other markings I can make out are 'DJER' with the number 41 underneath?
Are these basic stock tubes or better?

Thanks in advance for any help.

Don’t have any experience with little dot amps, my suggestion is to ask on the little dot tube rolling thread. Sure someone there would be more helpful.
