Lin - classic speaker guru par excellance and Rofiel - mono aficonado

Rofiel found this Jensen M10 field coil 13" driver (OEM WE TA4151 - more info) stashed in an ancient garage 120 kms. away from Manila

I revived the tube rectified  power supply with fresh Sprague ATOM capacitors. Since original replacement cones are unavailable, we took it to Lin for restoration.

The result of Lin's...

...painstaking labor.

To augment the top end, we added a phenolic diaphragm'ed Jensen RP103 alnico horn tweeter through a simple DIY crossover

Rofiel designed a Klangfilm inspired open baffle using phenolic plywood with piano hinged wings to maximize bass yet convenient transport.

November 2008 Hi-Fi Show

 Upon instructions from our boss, my first audio gig in Manila

 was to exhibit projects seen but never heard by the local audience. In particular - mono playback and Lenco idler drive turntables.

My wing man setup2 and BenC, a local DIY enthusiast added a twist on open baffle material...

...Philippine Tanguile wood planks, readily available for wood flooring, affordable, more rigid than plywood and even better acoustical properties.

Lenco L75 + Ortofon AS212, Garrard 301 and Thorens TD124II + FR64fx, 

MC step-up transformers: Altec 4722, Ortofon SPU-T1 and Tamura TKS83

JELdx preamp and SE300Bdx (driving 755C/OB)

Grease bearing Garrard 301 in laminated birch-ply plinth, Ortofon 309/SPU GME for stereo LPs...

...flanked at the back by the Philippine debut of a viscous damped Velvet Touch tonearm with cartridge slides loaded with a GE RPX and Denon DL102 for mono LPs.
