KT88 tubes for Monos
JJ has been doing some excellent work on KT-88s recently, in particular this one:https://www.cedist.com/products/kt88-jj-electronics-blue-glass 
OTL amplifiers
While the ZOTL amps are a brilliant design, they are very much not an OTL, as they employ an output transformer (see Dave Berning's patent).  
Tube Guru 6C33C Amp- Has anyone heard this amp??
It looks alright, but I think you will find it underpowered for your speakers (I have T-3s which are the same impedance and efficiency). I assume your room is bigger than mine since you have room for the T-1s. I recommend something with 60 watts i... 
Warm Sounding Preamp Suggestions
A tube preamp will definitely not be as bright. Brightness is often not a frequency response error as it is caused by trace amounts of higher ordered harmonics. 0.005% can be too much! Tubes tend to make less of the higher ordered harmonics and so... 
To Pre or not to Pre? Here is my take
^^ I’m not arguing that point; we don’t use coupling caps at the outputs of our preamps or amps as I previously stated.But most sources use them whether we like it or not. 
To Pre or not to Pre? Here is my take
^^ That's pretty unusual (and also explains why a PVC works in your system)!The problem you often run into with direct-coupling is the circuit can have bandwidth that can go lower than the actual power supplies (which always have some sort of time... 
To Pre or not to Pre? Here is my take
The issue is not what is the output impedance; whether its tube or transistor. The issue is that the output impedance can vary with frequency while not at the same time having flat frequency response into a certain load impedance. IOW the output i... 
To Pre or not to Pre? Here is my take
Even if there were engineering issues, forty years is more than enough time to solve them. Not to be a curmudgeon, but I suspect most of what is being engineered in wire and linestages are differences marketed to different tastes. This statement i... 
New Technics SL 1200 GAE
I think it's not easy to mount different tonearm on SL 1200 GAE or SL1200 mk2. It's impossible to mount "12 tonearm and most of the "9 or "10.5 inch tonearms (except maybe jelco, sme, audiomods, dynavector, rega etc) does not fit into position ... 
What settings do people use with Lyra cartridges?
The 100 ohm value suggests that your preamp is unhappy with RFI (Radio Frequency Interference) at its input.The 100 ohm value detunes the RF circuit caused by the tone arm interconnect cable and the inductance of the cartridge. As a consequence, t... 
New Technics SL 1200 GAE
If you prefer just the "look" of the SL1200 mk2 over the SP10mk2 then it’s a matter of taste, but you can’t ignore the fact that SL1200mk2 is not the hi-end turntable at all, in stock condition it’s a dark sounding turntable, not interesting at... 
Tonearm cable recommendations
If you are planning to use a LOMC cartridge and also plan to load the cartridge input on the preamp with a low resistance value then the choice of cable isn't going to be very critical. The main thing you will want to do is to look at the capacita... 
low power tube amp
If the speaker choice is still open, consider some speakers that are more efficient (that is if you are planning to keep the amplifier). I would be on the lookout for something in the 93-96db efficiency range; generally speaking its not a good ide... 
Power supply hum transmitted to loudspeakers
.. the faint buzz when your ears are within about 3 inches of the mid-range drivers or the tweeters is perfectly "normal".   Back to the hum/woofer... I submit that at worst, you should hear a faint whisper of air when your ear is essentially ri... 
Preamp popping!
@toddverrone Thanks for confirming my suspicion! If I recall rightly the RCAs are the 6V6s to be looking for.
