Telefunken V306 Vacuum Tube Amplifier - Under Repair - Partially Functional

I've moved and finished all the necessary arrangements, so I've returned the price to its original level.

I won this item on Yahoo Auctions intending to repair it, but I've decided to stop working on amplifiers mid-repair, so I'm listing it for sale.

- I've made all the knobs that weren't working at the time of purchase functional.
At that time, almost all the knobs were deteriorated, so I've temporarily attached chicken knobs. The original knobs are also included.
- The fuse holder was rusted and unusable, and not up to current standards, so I replaced it to make it usable. The power cable was an old, ungrounded 2-prong type, so I replaced it with a new 3-prong one.
- The input/output specifications are proprietary, so I've removed the microphone input, line input, and output sections and attached some connectors.
- Due to a faulty capacitor, there was abnormal voltage to the EL34 tubes, so I replaced the faulty capacitors with Panasonic film capacitors.
- I've included all the vacuum tubes that were missing at the time of purchase.
- One of the screws for the top cover was missing from the time of purchase.

It currently powers on, and all voltages are passing through the circuit.
I tested the sound once with the current output transformer, but the sound amplification was too powerful, so I couldn't fully confirm its operation.
I recommend attaching an output matching transformer first.

The input voltage can be selected from 110, 127, 220, or 240V.

It was modified by EMI to be used as a microphone preamplifier, and I was modifying it in the same way for that purpose.
If you change the output transformer, I believe it can likely be made into a microphone preamplifier.
I have reference materials and circuit diagrams that I will provide to the buyer.
Please repair it and use it if you have the skills.
