<|begin_of_box|><thinking>I need to carefully analyze the circuit to identify all components and their connections. 

First, I'll identify the components:
1. A voltage-controlled voltage source (VCVS) labeled "xV0" - it has a diamond shape with + and - terminals. The control voltage is V0, which appears across resistor R3.
2. Resistors: R1, R2, R3, R4
3. Capacitor: C1
4. Voltage source: V1

Next, I'll determine the node connections:
- Node 0: Connected to voltage source V1 (negative terminal) and resistor R2
- Node 1: Connected to voltage source V1 (positive terminal) and resistor R1  
- Node 3: Connected to resistor R3, capacitor C1, and resistor R1
- Node 4: Connected to capacitor C1, resistor R4, and resistor R2
- Node 5: Connected to resistor R3 and VCVS (negative terminal)
- Node 6: Connected to VCVS (positive terminal) and resistor R4

For the VCVS, since it's controlled by V0 (voltage across R3, which is between nodes 5 and 3), the SPICE format will be E x 6 5 5 3 x where:
- "E" denotes voltage-controlled voltage source
- "x" is the name
- "6 5" are the output nodes (positive first)
- "5 3" are the control nodes (where V0 is measured)
- "x" is the gain

The remaining components follow standard SPICE notation with their respective node connections.</thinking>
