Modifications
If you build using the stock chassis, a really nice upgrade is to buy pre-made front and
rear panels from
www.frontpanelexpress.com
(download files from
www.hagtech.com
). Another potential change is to replace the three 3.3uF film
capacitors with Hovland 3.0uF 200V capacitors from AES (#C-H3-200), although this
may not necessarily be a sonic upgrade. Alternately, you can add smaller bypass films to
these, such as your favorite audiophile 0.01uF to 0.1uF capacitor.
