Water Pump

visited a friend the day after Christmas. On the way home the water pump started squealing badly ;(

The radiator and fan had to be removed.


Old pump off - I hosed the water jackets in the engine block and cylinder head until the water became clear. Lots of rust.


New water pump to the left ready for installation.


Done - elapsed time ~ 2.5 hours

Altec 32C horn

I've been listening to this horn and liking it A LOT! 


The lineage of this horn can be traced directly to the Western Electric 753 monitor (scroll down).

More later ;)

Hashimoto HC-203U SE output transformer


In the past I have used a pair of H20-14U for the JEL SE10dx monos project and I'm also very familiar with the not quite so Simple 45 fitted with H20-7Us built by Setup 2 for the November Hi-Fi Show head honcho. Today I will report on the entry level SE OPT offering from Hashimoto.

 

Colors in Kanji


Technical and listening tests were conducted using the JEL SE2A3DX circuit.

Aside from a 3.71mm difference in lamination thickness and use of flying leads instead of terminals (U808) these two transformers seem to be technical and physical twins. But sonically they're not even distant cousins. The HC-203U is a bold performer and gives a front row presentation. Given its rather small stature, it has bass slam and definition that I associate with transformers twice its size. Vocals are presented in a lifelike manner and there is enough extension in the highs to give a sense of spaciousness and airiness. The Hashimoto HC-203U is what I always wanted the Tango U808 to be.

Fi


30 Watts Street
Soho, NYC
Winter '93

A short-lived (early 90s) Hi-Fi shop located in SoHo NYC owned and operated by Don Garber which featured amplifiers and speakers crafted by himself and other audio artisans like Noriyasu Komuro, jc morrison, Gordon Rankin, Herb Reichert, just to name a few.
