things are not looking good. tranny readings checkout ok. subok ng load test baka may bumagsak na section. so sorry pre, nothing good to report.

Tono Preamp to 12AU7 Unity Gain PreampIto pala ang concept. www.decware.com/linestage/zp1.htmSet up for a single line level source, this Zen Triode Tube Attenuator is superior sounding when compared to a passive preamp in most systems! It was designed for the serious audiophile in the spirit of "less is more!" We have found this unit to be synergistic with both SET amps as well as high power tube and solid state amps. In fact, if you have a high power solid state amplifier, this is an absolute must. interesting... sana nahiram ko muna bago naipadala sa zamboanga ;D baka mapagaya din ako eh ;D

Some lessons from our friends. 2 weeks ago... Jojo: "Jet, meron ba tayo session? Sagot ko na ang linestage preamp, dadalin ko sana yun skeleton ko na preamp para mapakinggan natin." Jet: "Wala pa schedule, ano maganda ba tumunog? Ano rectifier ginamit mo?" Jojo: "Kaya ko nga dadalin para ma test natin, ss rectifier ginamit ko." Jet: "Sayang naman yun NOS 5Y3GT mo, diba meron ka nun?" Jojo: "Meron ba ako nun?" Jet: "OO sira! Sa akin mo pa nga kinuha yun!" Lesson #1: Meron pala ako 5Y3GT na nos. Joel: "Walang cover yun preamp mo Jo?" Jojo: "Wala eh, skeleton lang, sort of experiment ko kasi siya. Dadalin ko nga sa session para madinig niyo - basta wag lang hahawakan yun mga parts, kasi baka makuryente." Joel: "Wala ka ba magagawang paraan para malagyan ng parang cage man lang? Kasi baka nakainom na sa session hindi makatiis - biglang hipuin yun preamp mo." Lesson #2: Takot si Joel makuryente. Lesson #3: Mag-ingat sa session pag nakainom na - baka makuryente. ;D ;D ;D Jet, ginamit ko na yun 5Y3. ;D Joel, hindi ka na makukuryente - gumawa na ako ng case! ;D

galing mo sir jojo... ganun talaga pagmaraming nang nainom umiinit ang mga tubo natin... kaya marami ng gustong hipuin. at pagnanghipo, ayun nakukuryente. parang line stage nga diba... ;D

May tama ka Vince, yan nga ang lesson #4. ;D
Joel, nahiya kasi ako sa iyo sa itsura ng preamp ko kaya ginawan ko ng tagpi-tagping chassis, pero ang pumirma talaga is yun baka may makuryente... o hindi mo lang ako nadiretso na ayaw mo makuryente? ;D ;D ;D
Joey, sa session pagusapan natin yan panghihipo. ;D ;D ;D
Henry, paki sabi na lang thanks dun sa babae naka blue na pa_ty. Oks na oks talaga yun nakuha ko sa iyo pre. Sana next time red naman. ;D

This may look like any other preamp that I have built - but it's not. Now let's have a tour and see what's inside that preamp... This is my psu section, using a tube rectifier in a CLCLC style filter bank. The first two caps are F&T's and the last one is a Nichicon cap, nothing fancy - just what I have laying around my parts bin. This here is the input section, a 6SN7 in the usual voltage amplifier topology but this time LEDs are used in place of cathode resistors and has an adjustable CCS as the palte load. Now for the output section, another 6SN7 tube with, of course, another pair of CCS boards. Output caps are what I have around - again. ;D Here they are powered and ready.
