Heath monoblocks complete, sounding very good (picture)

Posted by PeterI (A) on June 27, 2012 at 13:02:22

My Hk W-5M amp restoration has paid off. I'm hearing very good things. I haven't done a head-to-head comparison yet with my (on the shelf) Eico HF81. Maybe apples n oranges.

The new SDS board power supply settled ALL the voltages down, near spec. The tubes are happy, I'm happy. Things still breaking in, so to speak.

I wish I could get more gain - I seem to lose some with my passive preamp. At full volume, it's not quite as loud as it should be. Fewer resistors in the input to the first tube? (Mike said sumthin about 30uf bypass cap on cathode of 1st tube; was a concept I don't know about).

thanks for input (har, har)

Peter

bypass film caps - PeterI 07:56:35 06/30/12 (5)

I think there are better caps than the Solens . . - John PA 17:09:03 06/30/12 (4)

To me, everything is in the audio path but. . - John PA 12:23:58 07/01/12 (0)

Thank you; are there affordable alternatives in those sizes? and 600V? NT - PeterI 17:15:57 06/30/12 (1)

In the physical size, not so much. If you bypass them . . - John PA 21:08:51 06/30/12 (0)
