Hard-to-get parts for the Hummingbird/Calliope Amplifier
A small set of parts for the Hummingbird Amplifier which constructors might find difficult to obtain otherwise.
The set includes two driver transistors (MJE15034G & MJE15035G), a VAS transistor (KSC3503DS), a 220pF 250V C0G ceramic capacitor and two 0.22Ω 5W resistors of the type specified in the parts list.
The PCB is available for purchase separately on our website. The remainder of the components can be obtained from a retailer like Jaycar, including the MJL21193 & MJL21194 power transistors.
Keep in mind that Altronics have a complete kit for this module (Cat K5158).
Note: photo shows fully assembled module, including parts not included in this set.
