Shure Mic Transformers

Ben C was hunting for Altec 32s, Emilar EH800s
and EH500s at Jammin' Jersey

Tipped off by my buddy, Ben C (dude in the middle), I scoured eBay for Shure Mic transformers that can be repurposed for MC step-up duty. These transformers typically sell for under $50/pair shipped within the USA.

They don't have model numbers so I'll identify them based on their step-up ratio.

Lens Filter Ring Vise

I recently fixed two lenses from my collection which had dented filter rings using this $36 tool from Micro-Tools.

The tool didn't come with instructions but using it is pretty straightforward. As a precaution, I covered the front element with cardboard. First, I positioned the moving jaw of the tool on the dent and aligned the threads from the jaws of the tool to mate with the threads of the filter ring. Then I gently spread out the jaws of the tool to press out the dent. I cannot over emphasize going slowly but surely!

Dent was between 10 and 11 o'clock
impossible to fit a hood or filter

After the procedure, a 46mm
screw-in lens hood fits with
minimal fuss

Dent was between 3 and 4 o'clock

Not perfect but better than it was

The tool has paid for itself ;)

Noguchi Finemet: FM-3WS-H + FM-6WS output transformers

This was the last extensive testing and listening session I did in the attic before we moved back to the states. I misplaced some data and just recovered them recently. So as promised in a previous blog entry, here's the write-up on the two entry-level SE Finemet OPTs from Noguchi.

WARNING

These are bonsai-sized output transformers. If HUGE iron + HIGH inductance and thumping bass frequencies is your idea of high-fidelity you should STOP 🛑 here!😉

However, if the finesse and realism a WE/Altec 755A can provide within its 70-13 kHz bandwidth is your idea of a GREAT time, please proceed!😊

Noguchi FM-3WS-H

Noguchi FM-3WS-H + Tamura F7004

David vs. Goliath - indeed, the FM-3WS-H is tiny. I had to mount it on a perf board so that it wouldn't fall from the square mounting hole left by the Tamura F7004 ;)

Harrisburg Hamfest

After playing the first concert for the July 4th Summer Series with Harrisburg Symphony, I received a text message from a friend that there was a Hamfest in town on July 1st.

The venue was only 10 minutes away from our hotel.

Pick of the day!

Spring 2017 Camera, Hamfests and Radio Shows

Kutztown Radio Meet

May 12-13, 2017

Kutztown, PA

I used to frequent this radio show until I left in '08. It used to be a relatively small event but has evolved to the biggest radio show in the east coast.

Contax II + Helios 103
Foma 100 in Rodinal

A pair of MC60s + a Dyna PAS 3 preamp

RCA preamp/mixer + 2 x Rek O Kut B12s

My friend Larry's booth featuring handcrafted and modified tube preamps and amps

Mike used to sell vintage audio but has shifted to classic/vintage film cameras. An avid music lover, he still listens to a hifi system using carefully chosen classic equipment.

Got an EV MC12, loktal triodes, 6C6 pentodes, a 10Y and a Ciro-Flex C TLR

Classic cars in the field

Photorama USA

Centreville Moose Lodge

Fairfax, VA

Fuji X-E1 + Voigtlander Heliar 15mm f4.5

Twenty some years ago I frequented Photorama shows in the Washington, DC/Baltimore area.

Fuji X-E1 + Voigtlander Heliar 15mm f4.5

This was a good place to source classic cameras, lenses and accessories during pre-eBay days. Since I've been in the market for a Sonnar 50mm f2 or f1.5 for my Contax II, I thought I'd try my luck at this event...

Fuji X-E1 + Voigtlander Heliar 15mm f4.5

Even if the show was only a fraction of what it was 20 years ago, I did find a nice Opton Sonnar 50/2 with a dead Contax III (good for parts) rear lens cap for less than the going rate on eBay.

Icing on the cake: Tewe Zoom finder, Paterson Tank, a book and freebie expired TX400s

Radioactivity 2017

June 15-17, 2017

College Park, MD

From the early 90s until '08 I attended this event regularly. Many of the tubes, transformers and chokes I am still using in my hifi system came from this radio show.
