12AX7A preamp tubes - ribbed vs smooth plate
I thought preempt tubes were a way to describe use of this tube within an amplifier (ie taking the week analogue level signal from the pre-amplifier and turning it into a stronger line Signal) and is this also considered to be a signal tube? I’... 
12AX7A preamp tubes - ribbed vs smooth plate
. . . ohhh, so they are MC9011s? I just did a cursory read on them--interesting amps.  Anyway, Mac is calling the two 12AX7s the signal tubes for the amp.  Which is not what I would call a "preamp tube"  (I would call a preamp tube a tube in the p... 
Are there other people like me ? Amazed by their low cost system :)
I will really like to hear others people experience with a relatively low cost piece of gear or a relatively low cost system... "relatively" means the price matter not, That’s an interesting definition of "relatively." So if the cost doesn’t m...

It's a mono block amplifier with 8 KT 88 and 6 small tubes (  4 rectifier, 2 preamp). I assume the "2 preamp" tubes are the amps input tubes or driver tubes?

I guess the "Made In China" thread was the lastest to bite the dust. . . . (I wonder why.)  
12AX7A preamp tubes - ribbed vs smooth plate
@immatthewj amps use a variety of small signal tubes in their inputs it's also possible the OP is referring to an integrated amp. If this is the same amp(s?) that OP was referring to a while back ago with (I think I remember him saying) 16 outp...

"The lady doth protest too much, methinks" Ha ha!  
How important is the efficiency of a speaker to you?
If you want/like 8 ohm 86 dB sensitivity speakers you will most likely have to go with a high watt output solid state amp (>150 watts).  It takes 150 wpc plus (ss) to drive a speaker rated at 86 db?  
How does a preamp die from sitting unused for a few months?
OP, did you solve the mystery?  
B&W 802 D2 Capacitors Worth Upgrading?
@allenf1963 , I think that part of the tubed pre in front of SS amp appeal might be related to heat and maintenance. Meaning that an amp that utilizes output tubes can run pretty hot and also requires occasional bias checks & adjustments and a... 
Don’t look for perfection.
I have a tendency to immediately dismiss a record if I hear a flaw, Your standards are higher than mine.  I respect you for that.

Alan Parsons Project got a thread killed?  Seriously?  I could understand it if it was REO. . . .

Went through a few posts here and the only conclusion I came to is that you are offended by whatever words others choose. +1 @milpai  .  
Audio Research Replacement Tubes
I have always noted that when my output tubes were getting tired or sick I would start getting goofy bias readings.
