Hello all. I'm getting ready to start a First Watt F3 build and have a few questions about some components. On a scale of 1 to 10 I would rate my knowledge of electronic components at a 3 so take it easy on me. I just want to make sure I'm not buying the wrong stuff.
For resistors I'm using metal film where possible, metal oxide for higher wattage resistors and ceramic where that's all I can find. Is this ok?
For the potentiometers I'm using these. Are these OK?
Family Rotary - Linear
Resistance In Ohms 5.00K
Power (Watts) 0.25W, 1/4W
Will this work for the inrush current limiter?
Family Inrush Current Limiters (ICL)
R @ 25°C 15 Ohm
Current - Steady State Max 3A
R @ Current 0.335 Ohm
Tolerance ±20%
Is this bridge rectifier ok?
Diode/Rectifier Type Single Phase
Voltage - Rated 200V
Current Rating 35A
Package / Case MB-35
Packaging Tray
Speed Standard Recovery >500ns, > 200mA
Thinking about using this transformer:
AVEL's Y23 series power
¤ Load Capacity: 160 VA ¤
¤ Secondary Voltage: 18V + 18V ¤
¤ Dimensions: 4.0" D x 1.7" H ¤
¤ Weight: 3.3 lbs. ¤
Probably will use a stepped attenuator for volume control. Hopefully it all works out ok. Seems a little overwhelming right now but these projects normally seem to come together with parts in hand. Thanks for any help and thanks Nelson Pass for your great contribution to the DIY community.
