Both have been used in the past with no issues. A trimpot is used to allow trimming the DC offset.
Parts used for both include:
Amp#2: The other set of boards is kind of a mini Aleph 30 with IXYS IXFH74N20P output transistors. Tested at 24V rails with about 1.3A bias. $50 for the set. See second image.
Buyer to cover actual shipping cost. Will generally ship with the cheapest carrier unless otherwise requested. Payment by PayPal. Friends and family appreciated to avoid the fees, but left to the discretion and comfort level of the buyer.
Parts used for both include:
- Vishay/Dale military spec RN series metal film resistors
- Panasonic metal oxide 3W resistors
- Elna Silmic II electrolytic capacitors
- Silver mica feedback capacitor
- Zetex input MOSFETs
