i know this phono pre has been around for a while, looking for tweeks, tube improvements, or any other things that can be done for this fine piece of gear, i am trying to chose between a ps gcph and the 834p, both are stock no mods, the 834 has telefunken tubes
Talk to Mitch Singerman, he is an expert at modifying the 834P. He will be able to give you some good advice on it. I believe his mods include Hovland caps and JJ tubes, among other things.
Herbies Halos are the ones I use one all my tube gear inlcuding phono stage. These have an excellent reputation. There are also tube rings of various shapes and materials, such as rubber, brass, or silicon.
