New models coming soon:
AMP4, 2x50W 8 ohms, integrated power supply
=======================================
- Based on the Tripath TK2050 that runs of a single 20V to 35V supply.
- AMP4 has an onboard power supply rectifier and bulk capacitors and +5V supply. Just add a transformer.
- The two pice TK2050 chipset uses the Tripath TA2001 signal processor chip and the TP2050 power chip. The TP2050 chip has the same footprint as the TA2021B chip used in AMP3. The TA2001 is the same processor as used in AMP2.
- The TK2050 THD+N datasheet values are exceptionally low, 0.007% at 30W, 8 ohm.
- AMP4 is optimized for 6 and 8 ohm loads, not so well suited for 4 ohm loads.
- Most components for AMP4 are surface mounts. The footprint is 50x120 mm.
AMP4 will be available in august/september.
AMP5. 2x100 W 4 ohm. Only hole mount components, power supply on board
=================================================================
- A "complete" amp based on the same chip as AMP1, the Tripath TA2022.
- AMP5 has the power supply on board, just add the transformer. It also has as a stabilized +5V supply on board.
- The board has a pushbutton volume control chip that should be as quiet and and low distortion than virtually any mechanical pot.
- The first prototype of AMP5 is playing now. Good news if you do not
like to solder small surface mount components as AMP5 uses only through hole mounted components.
- The footprint of the board is 82x150 mm
AMP5 will be available in august/september.
- AMP6. 2x25W 4 ohm. Hole mount components. Stabilized power supply on board
==================================================================
- Based on the Tripath TA2020. The chip is very similar to the one used in AMP3. The difference is that the TA2020 is hole mounted.
- This amp is good news if you are interested in AMP3 but do not like to solder small surface mount components. AMP5 uses through hole mounted components. There are a few large surface mount diodes but these are larger than the hole mounted components in the kit.
- Stabilized 14.6V 5A power supply on board. Just add a 12VAC transformer.
AMP6 will be available in august/september.This looks really good for the DIY folks who would like to build one of these amps, but did not want to deal with SMT components.
It is also good for me if I decide to offer any of Jan's amps already built into a chassis. It gives me more freedom to choose upgraded parts
