tubes for Vicky Bassman

blues · April 10th, 2004, 01:21 AM

I purshased an rca 5751 tube for the first preamp spot,the amp had an electro-harmonix 12ay7 in it when I bought it.The guy I got the tube from threw in a phillips jan 12ax7.My question is how do the other preamp slots affect tone,is the second spot for the bright volume control.What is everyone thoughts on the jan phillips 12ax7.
I think the electro-harmonix 12ay7 is a pretty decent tube.Alot cheaper than an rca for sure.In the other preamp spots I have 2 groove tubes,they sound pretty good also,I was surprised.I did not hear much difference between the phillips and the groove tube in the second position,the phillips sounds a bit brighter.
I have not heard rca 12ax7s and was thinking about trying some.Can anyone help me out here,how does the rca sound compared to phillips?
Thanks Dave

I prefer 50's GE's in the preamp slots and a 50's RCA 12ay7 in the first position, then some Tung Sol 5881's, or JAN Phillips or Sylvania small bottles, then a NOS rectifier preferably Mullard or GE, then sit back and enjoy the tone.

Reviews are admittedly subjective, but click on the first three links here for some good comparison tests between various tubes, including a variety of 12AX7 and 12AY7 brands. Hope this helps, CS :-)
