This one?

I am looking for tubes for cdm but all sold out@alo audio web site...any idea where I can get these tubes or anyone else is willing to sell?thanks

Got it! I’ll check it later,thanks for helping me out:)

But the led act normal when I change back to stock tubes,so I assume that’s the problem of my aftermarket tubes,not the pcb of cdm

Yesterday I was listening to my CDM and suddenly the led of the tubes turn off,but still,there was sound came from cdm. Does it means my tubes died already?

Compare to 1.19?

Not possible?Anyone got the 1.16 hex file?

The difference between 1.16 and 1.19 is day and night...

Anyone can share the previous firmware hex file??

My 2000ob came with 1.16 when I purchased and I upgraded to 1.19, Is it possible for me to roll back to 1.18 like you mentioned?also where can get the 1.18 hexfile?i have searched around the forum and couldn’t find it,thanks a lot.

Thanks for replies,I just got the device recently and still burning-in.Till now just around 80up hours

Compare to sp1000ss,my 2000 OB seems have less bass,is it normal?

For me,Layla II doesn't sound the same as Layla I..and the difference is quite obvious
