My McIntosh MC225 now sounds wonderful


When I acquired my McIntosh MC225, the tubes that came with it were near end of life. I wrote an email to thetubestore.com looking for recommendations for a new set of tubes for the MC225. I received an email back that recommended :

Preferred Series 7025/12AX7,
JAN Philips ECG 5814A/12AU7,
Electro-Harmonix 12BH7,
Tung-Sol 7591A.

I ordered the tubes in the correct quantity. For the first 25-50 hours on the new tubes my MC225 sounded harsh. Then it got that sweet tube sound and I found out how incredibly wonderful a McIntosh MC225 sounds. I have recently ordered a spare set.
