Tube recommendations

Hi all
The phono stage within my pre currently uses these 3 stock tubes - Sovtek ECC83, Electro Harmonix ECC81 & ECC88 (I think it's Tung Sol).
As I'm new to tubes which tubes would you recommend to be a significant  upgrade?

Thanks 
Rich

@tzh21y Thanks for the suggestion. 

@nsp - the number on the tube is 6H23 & underneath that is 9202.

+1 Telefunken NOS or you could go modern Gold Lions (honestly they can be just as good). Both will fit your application (low noise & detail).

6H23 is a Russian tube type but a 6992 can be substituted. These tubes are very revealing and have an extended top-end. 
  With a phonostage it's important to get tubes that are low-noise and tested for microphonics. The 6992 is a tube that can become microphonic.

It seems as though the 
Voskhod 6H23 is a very in-demand tube. I would roll the other tubes and keep this one for now.

@shadorne  thanks, yes I think it will be going the Telefunken route.


@lowrider57  thanks. I did notice that they are about $130 so can't be that bad...!
