The 2225 power supply uses a [[120-1630-00]] mains-frequency toroidal transformer to produce a 60 V DC supply, followed by two TL494-driven switching regulators. | The 2225 power supply uses a [[120-1630-00]] mains-frequency toroidal transformer to produce a 60 V DC supply, followed by two [[TL494]]-driven switching regulators. | ||
The scope uses transistor array ICs like the CA3102, [[CA3046]] and CA3054, but no Tek custom ICs. | The scope uses transistor array ICs like the CA3102, [[CA3046]] and CA3054, but no Tek custom ICs. | ||
