Eico HF-81 with Klipschorn

I have no idea what you are talking about. I checked that I have a pair of Eico Mullard small tubes in middle position made in Britain (England). I wonder where I can buy any replacing tubes when they burn out with reasonable price.

Thanks Dfhaleycko for your information. I love my true system very much. My wife is happy with my expense after selling Mark Levinson No. 23 and 28 and B&W 801 Matrix series 2. I am surprising that using old MIT Tube MH750 speaker cables (costing $150) making Klipschorn singing with different level comparing Transparent MWS10 Super Speaker Cables. For pure analog, my Linn Sondek LP-12 makes Klipschorn singing more warm, light, and soft vocal, especially Partial Barber and Diana Krall. I am thinking about upgrading my Klipschorn crossover AA. But right now I am short cash for my remodel my house and wife factor controls finance. I can only afford buying crossover less than $150 sale including shipping. I can wait for right moment looking at used AA crossover for sale.

I recently upgrade new Cap 12uF and 2uF for crossover ($80 for upgrade crossover kit). I followed procedures on www.critesspeakers.com/crossovers.html. The sound is big difference when I play LP with more details on vocal and bass deeper than before. I hooked up Klipschorn with Dynaco ST70 and PAS3. Sound is much warmer than Eico HF81. For vocal, HF81 is winner as EL84 but ST70 with EL34 is classical symphoney.
