Leitz 8-Element Summicron 35mm f2

While organizing my Flickr, I noticed that I've uploaded over 700 images taken by the Leitz lens I use the most - the first version of the 35mm f2 Summicron. I've blogged about this lens in the past when it was merely an old user lens, which took very pleasing images.

However, in the recent years, this 8-element lens has caught the attention of aficionados,  skyrocketing its value. In fact a reverse engineered version of this lens is being remanufactured in China in limited quantities.

It's not a razor sharp optic and the corners vignette wide open.

I like the way it creates an illusion of a three dimensional image with a smooth bokeh.

It's sharp enough to capture essential details with good contrast.

Subtle tonal gradations are well preserved by this medium contrast lens.

The technical limitations of this lens contribute to its overall character and charm.

I like how this lens tames a digital sensor, just like I utilize vacuum tubes + transformers to turn a number crunching DAC chip into a musical device.

I love seeing the tonal quality of my hifi through this lens.πŸ˜‰

Bonsai X'mas Tree + Amp


Looking back to 2022


To celebrate the holiday season I've prepared a short video. Please note that given the dynamic compression and bandwidth limitations imposed on sound quality by YouTube, I upload videos for the visual aspect rather than their sonic merits.😊


Turntable: Garrard 301
Tonearm: SME 3012 
Phono cartridge: Supex SD900 + conical stylus 
MC step up: Altec 4722 
Bonsai Amp: 720mW per channel SE 171A, coming soon! 
Speakers: Altec 753C

So watch how the 720 milliwatts per channel Bonsai Amp is pushed to soft clipping by Tchaikovsky's "Pas de Deux" from "Nutcracker" driving the Altec 753Cs. πŸ˜‰

Thank you to all my readers and supporters!

πŸŽ„πŸŽ„πŸŽ„Wishing everyone happy holidays and a great new year!πŸŽ„πŸŽ„πŸŽ„

JEL Loctal Phono Preamp + Tube Shields

 

It's been over five years since I built this loctal preamp. I moved it recently so that it'd be between my two turntables. In this location, I was surprised by higher-than-usual hum and noise levels emanating from the phono section especially when compared to my RCA octal + 76 line stage

Given that it had been playing quietly and flawlessly until it was relocated, I was dumbfounded. Then I noticed that when I put my hand close to either 7F7 tube, the hum and noise got even louder.πŸ€” 

Before taking the preamp out of the system for a thorough check up on the test bench, I searched for a couple of tube shields from my parts bin. 

Voila! The unusual hum and noise vanished.πŸ‘


Sit back and enjoy Alice Coltrane's "Blue Nile" from her album "Ptah, The El Daoud"! π„ž π„’πŸŽΆ
