So, I now learned my lesson to be very careful with T2 and tubes. I couldn’t deal with Groove tubes EL-34 sounds, and while I liked the JJ on the Grounded Grid, it was too fragile to stand with T2. Never again to stuck any JJ in the T2 anymore.
Then nervously sticking in my next favorite in-line from GG tube rolls, the Quad RFT Vintage EL-34. Didn’t dare to swap tubes without checking the balances and offset. So balances was sitting at below 0.5V on both channel, and Offset was 5-6V on both channel.
The one thing I always noticed about GG and the T2 is that these output tubes affect the “turned on” to the 009. The Groove tubes did an echo sound when Hv kicked on, and quick crack when turned off. The RFT has a quick snap which is lower in volume than Groove tubes, and echoes when turned off. In the GG quad Apex matched from JJ was dead quiet on turning on/off. Sadly, it is not a brand to stick into the T2. Now, why would they behave that way ? I have no clues.
anyways, I am enjoying the T2 with Quad matched ECC88 goldpin from JJ...again, love those JJ signatures. Cross my fingers, and pray that they don’t give problems, and now RFT Vintage EL-34. I just had to get away from bad tubes Signature, but also so much respect to how powerful T2 is, and that she can cook tubes easily.
So far, T2 is awesome!!! Wooooo
By the way, if any long time T2 owners can please share the experiences of reliables tubes, and bad tubes. I think it would be excellent !
