Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for a hardware engineer capable of diagnosing and repairing an already designed and built amplifier circuit. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Research 3. Diagnosis 4. Test & measurements 5. Review and discussion of discovered problems and their solutions Important notice: If you happen to send the circuit board at my workshop, then you should be aware that all freight costs (in both directions) are covered by the employer. Important notice: The proposed delivery schedule regards only for the time of receiving the board. Transportation schedule is not included in the proposed delivery term. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov
