Rick, are you going to put new tubes in, or are you going to run the stock ones for a while? No UPS today... Perhaps I'll get the preamp wed.?
Thanks,

Mac 275 questions........
After some months of up's and down's with my ASL Hurricanes (just seemed to never stay operational for longer then 2-3 months) I have decided o retire them and get the McIntosh MC 275 (2 amps).
I have some questions for you all and appreciate any input you may have (especially form Mac owners) but opened to all.
My speakers are Infinity RS 1-B's and I will be using the amps to drive the top end of the system (EMIM's and EMIT's). I have a Perreaux 3150B for the bass columns. The Infinities are rated at 4 ohms.
I plan to listen to one amp on top ( I will get one amp in a week) and then when I get the 2nd amp ( a week later) run both in mono.
What will I hear with each application? First with one and then with both? Also can any of you let me know if any of you compared the Mac 275 (in mono) 150 watts with the Hurricanes 200 wpc? The Hurricanes were great but I just could not live with them being up and down so many times.
Thanks to all for your input.

Lapierre -- The reissued GL KT88's are a good choice from what I hear, and cost about $200+ for a matched quad. The PentaLabs/Shuguang KT88SC's which I tried (and liked) are just as good according to many, and about half the price. Try Doug's tubes http://www.dougstubes.com he's very nice, has reasonable prices, and he sells both. For the AX's and the AT's, NOS Telefunkens are the minimum place to start. THE 12AX7's AFFECT SONICS THE MOST. There are three of them (V-1, V-2, and V-5) If you are using balanced interconnects (which you should be, with the C46) then the first 12AX7 (V-1) is not in the signal path and so it can be any ol' 12AX7, just to complete the filament circuit. The first tubes I substituted (for the OEM tubes) were a pair of ratty old TFK 12AX7's (in the V-2 and V-5 spots) and the difference was really amazing in all respects -- air/ambience, detail, dynamics, soundstage/imaging, good hi and lo freq. response. Then came the TFK 12AT7's, and finally a quad of the Penta KT88SC's. The total should run about $300 - $500 depending whether you buy the TFK's on eBay or through an online tube seller. It's hard to beat NOS Telefunkens, but you can. Particularly by substituting Sylvania or RCA 5751's (triple mica black plates) for the 12AX7's. But the price/value ratio starts to go down as with all things audio ;-) (A pair of Sylvania 5751 TMBP goes for $150 or more these days -- but boy do they sing!) You might want to read the 12AX7/5751 sections of Joe's Tube Lore, if you haven't: http://www.audioasylum.com/scripts/d.pl?audio/faq/joes-tubes.html . |
