Hi: I am looking for a good source to get a matched pair of 3CX800A7 or even a pair of 3CPX800A7. Can be good pulls as I am quite sure a new pair would break the bank. Maybe you have what I am looking for and you are thinking of doing an upgrade to another amp with different tubes. Tnx. 73 De Mike VE3YF http://www.ve3yf.com
