Can anyone suggest the following:

1. A simple GDO circuit whose components are cheap and available in India. The GDO is much needed to tune coils for NR60. Are commercial GDO available in India? KIndly suggest where and how to get it in India.

2. A cheap but a good substitute of BFW 10 that is available in India. BFW 10 that are currently available in the market are priced very high. Rs.150 per piece in Delhi.

3. A cheap substitute for BC 178.

4. What care/precautions one needs to take while handling, soldering, and desoldering BFW 10?
