دوستان همونطور که شاید بصورت اتفاقی به این مطلب برخورده باشید، دوست بسیار عزیزم آقای مرادپور اقدام به ساخت آمپلی فایرهای لامپی منو بلاک با لامپ 211 کردند که در نوع خودش در ایران نمونه بوده... میتونید اصل مطلب رو اینجا مطالعه کنید... من افتخار داشتم یکی از مدعوین تست این آمپلی فایر باشم:

متن این نقد و بررسی:
I'd very much like to write some paragraphs about what Aref has built because I was one of the invitees on the demonstration session... you probably want to indirectly imply that inter-stage chokes were bought from abroad... but that's not right... weeks of time spent to twist wiring each by each stride... maximum care has been taking... let's get back to the main issue.. where was I? Oh yeah... testing day ..... to make it understandable I need to go back two months... I just came in sooner, more of the same... Aref just arrived right at time... a polite young man with his friend... two very big and well packed wooden boxes sat on the studio's floor... took some minutes to unwrap them... two recently born infants came outta boxes... looked shining... charming... they were place the the setup and turned on to warm up... after twenty minutes or so the tubes were pretty high...but thinks were about to get even warmer... with the sound...
"Let's get the show on the road" I said and it was checkout time... we were all anxious to begin the sequence of tests... OK... here we go...
first tracks started... sound was just amazing... low-db manger speakers was being handled so well as there was no tomorrow... the volume of sound was pretty high as every man jack would think the roof was just about raining down... sound stage was great literary... I was tied to the chair... I had been given the best seat, front row... center... in the middle of sweet point... we could hear the first fringe touch of the violin arch on the chords... the bass was pretty tight... I have not listened to few sounds... but this one was not a bit but to much different... the timber accuracy of the tubes were just adequate... Manger is so swift... but mono blocks worked the testes out very good... I mean it... really good.
the build quality was eye-catcher... the face was built from plexiglass which laser did the engraving on them... binding-posts were just in the place... gold-plated... tubes were all well-placed... electrostatic painting all over the deck board... a piece of high-quality and darkened wood was dominating looks at the first glance.
all in all it was pretty hoping... nothing wrong... everything was as would be.
someones want to belittle this nice job but I'm afraid, I have to say the reality... even it's a sore one (hey you... I'm talking you... yeah... you yourself )
