Kpinneo. Further to the above thread.... I was reviewing what I had written and clicked the submit button by accident. Anyway.... The re-wiring for mine is a little more straight forward considering I only need to unsolder and re-route two wires. I am assuming here that you have some soldering skills,basic electronic fundamentals and a little experience with vacuum tubes in general. If not; I would suggest you work with a local techie or a modder to do the change for you. Furthermore: You will have to run the extra wires with the top caps either/or from the underside of the preamp and up the sides to the connections on the top of the 7193 or drill holes beside the tube socket to route the extra wiring needed. The wiring and pin connections for the 6sn7 is somewhat different being it has two triodes sections. The heaters [pin 2 and 7 ] or the same for both tube types. The cathode [pin 8 ] is also common to both tubes. Remember the 7193 is a single triode so one triode section of the 6sn7 will be unsoldered at the tube bass. The unsoldered wires will be at pin #2,3,and 4. Those wires should be folded and labelled. The connections for the 7193 should be as follows: Pin #8 is wired for the cathode, pin #7 is wired for the heater. Pin #6 will be unsoldered as this wire will need to be re-routed to the top of the tube and a top cap soldered to it. Pin # 5 is the anode, unsolder and re-route the wire to the top cap of the tube. Top Caps must be snug at the tube connection. Always mark the wires for identification for converting it back. Remember, the gain of the preamp will now be 1/2 of the 6sn7 unless you use a pair for each channel. For those that want to use the standard 6j5 and equivalent subs....leave the connections as they are at pin #5[grid] and pin #6[anode] and unsolder pins #2,3, and 4. Please note: I will not be held responsible for any damages to your equipment as a result of this post and I would strongly suggest you consult with mick at supretek before you proceede. Hope this helps and best of luck.
Supratek Tubes and Tube Swappin' for Everybody
I will have a Supratek Chenin in my set up in a day or so. Since so many folks are rolling tubes around here I was hoping to garner a comprehensive list of everybodies favorite tube compliments. Be it NOS or NIB or WLATB (Whatever's layin around the basement)
Being that the "Deal of the Century" thread is a little more like a novel I figured this would be a good place to post questions and answers related to one subject of Supratek amps and pres.
On to the subject of me. I don't have immediate plans to swap tubes as I've figured that Mr. Maloney would supply us with something listenable for the break in period. But, since so many have reported such dramatic improvments I want to ask this question:
What is your favorite compliment for quietest gain and dynamics in the phono stage?
I will be using the Chenin exclusively for vinyl ( I don't have a CD player) and listen to loads of early rock and roll and Jazz bands, smaller jazz bands mostly, quartets and quintets. Some classical, the usual Beethoven and Mozart, but usually just a lot of loud garage rock.
Ok, now lets see what happens.
