My tubes dealer finally has available two octets of Gold Lion KT88 Platinum with the value of Ip and Gm respectively 80/81 and 8,700/8,700.
Are they good values for my two MC2301? |

Massimo.......I was at Ivan's Cape home, and helped him the day he put Gold Lion KT88's in both of his MC2301 amplifiers. Even with the tubes being brand new with no hours on them they were an improvement over the stock tubes. I noticed a deeper sound stage with greater definition of each instrument and voice immediately. We were playing both CD's and vinyl, and the sound was spectacular. I haven't heard the amps since that day, but Ivan has said the Gold Lions have opened up beautifully. In my opinion, you will be thrilled with the improved sound quality using the Gold Lion KT88's.
I had a similar experience when I replaced the stock tubes in my two MC275 MkV amps that I am running in mono. The Gold Lion KT88's opened up the amplifiers in the same way, with a larger, deeper sound stage, and more air around every musician and singer. I am so pleased with the Gold Lion KT88's that I have since replaced all the 12AX7 and 12AT7 tubes in both MC275's with Gold Lion tubes. These amps sing like never before.

I have all Gold Lion on MC275 and C2300 and I am very satisfied. I wanted to know if these values of Ip and Gm were good. Your KT88 tubes what values have? |

Massimo.......I don't know what the transconductance numbers look like on a new Gold Lion KT88. Perhaps Michael at Analog Tubes will chime in.

Massimo,
Gm of 8700 for KT-88's is high (good!) I would guess that these have been specially selected at the factory for high transconductance.
