Nice. Thanks Dave!RACKSYSTEMS":3iezh9w5 said:No issues with either. Just bias.
Yeah I’ve never tried 77’s. Maybe I’ll give them a go.fusedbrain":ewn1h0nq said:I've tried JJ kt77s in my BE100, as well as a few other el34 amps. I find the Kt77s give you a little more bottom end, are a little brighter, and sound / feel less compressed in the midrange vs el34s. More modern if you will. They drop right in and bias up no problem.
I would suspect kt88s would be a similar sonic change, but possibly even more pronounced than the 77's. KT88s will also require considerably more bias voltage, so I would expect to have to modify the bias circuit with a resistor swap.
Man let me know how they sound in there. Hopefully that gets it sorted.MetalHeadMike":ewn1h0nq said:Got a quad of KT77s coming for the QR!
