- Greetings:
-
- A few questions:
-
- 1. Can anyone recommend a decent mailorder source for hafler stuff?
- I'm looking for one of the smaller amps (for background listening
- in a small room): the 9100 or 9300, not the trans-nova products.
- My local dealers insist on selling for full MSRP, so I walked!
-
- 2. Does anyone know where I can get some (maybe 10 pairs or so) of
- these Toshiba transistors (IGBT): GT20D201 and GT20D101. I'm not
- having much luck with the local dealers. Maybe there's enough
- people looking to suggest a group purchase?
-
- 3. For you folks making class-A or high-powered amps, what do you do
- for heatsinks? Is the only way to get "Threshhold like" heatsinks
- to buy a Threshhold amp and gut it :-) ?
-
- And one suggestion: for folks looking for a great homebrew linestage
- (and are not afraid to tell your friends you can listen to op amps :-) )
- the AD744 (sans out stage) driving the AD811 as suggested in a recent
- "The Audio Amateur" and the Analog Devices Design Seminar handbook) is
- hard to beat!
