    Tube Change/Biasing a Stax 006t II

    New tubes tend to wander like that, no worries. When tubes settle in then ratings tend to stabilize, so a round of fine-tuning could be in order. These units are clearly not meant for tube rolling.. The trimmers are really that bad.

    The Entry Level Stax Thread

    Thanks for the clarification. I had a quick fitting with the JJs and some short CBS bottles. The JJs would certainly need case modification but the short types do fit (barely) with 90° angled adaptors.

    The Entry Level Stax Thread

    I can confirm these instructions also work for the SRM-500t. To remove the cover you will need a philips screwdriver for the side panel and torx T5 for the top panel. I did not manage to get balance stable under 1 volt as the tubes keep wandering multiple volts. Also in stock setting it read...

    Update: Finally settled with OPA627AU opamps in both the DAC and AMP stages.

The bass with the OPA2227PA...

    REVIEW: Matrix Cube DAC

    Quote: Yes, that's why I looked for a local seller also. There is valuable information in this thread. I would say make a selection from opamps to try out - buy a few at once better then pay shipping again if an opamp does not work out. Opamp swapping makes a difference. I am...

    REVIEW: Matrix Cube DAC

    Opamp rolling rocks . Using OPA2227PA instead of standard OPA2134PA. Begone harshness & welcome balanced analoge sound.
