For archive (Updated on February 26, 2019)
In the 50’s and 60’s, Ampex tape recorders (and similar) were used at the Burma Broadcasting Service (BBS). Akai, Grundig, and Sony were some brands used at homes for recording.
Sixth Buddhist Council
During the Sixth Buddhist Council, BBS broadcast the sessions where Mahasi Sayadaw U Sobhana served as the Questioner and Tipitaka Mingon Sayadaw U Vicittacara served as the Reciter/Expositor.
Recording media and formats
The archives are being offered as dhamma dana in Audio CD and MP3 formats. Sadhu, sadhu, sadhu to those who are trying to preserve, practice, and propagate the sasana (Teachings of the Buddha).
Individuals and organizations formally and informally tried to archive the teachings of the Sayadaws.
Sun Lun Gu Kyaung Sayadaw
Recordings (dhamma talks, kammavaca, …) of Myingyan Sun Lun Gu Kyaung Sayadaw U Kavi were made by his disciples. They can be downloaded from the Sun Lun web site.
U Sway Tin and his dhamma colleagues recorded 500+ talks of the Mogok Sayadaw and also transcribed the tapes for distribution as books. The advances in technology make possible the redistribution of the archives as Audio CDs, MP3s, and e-Books. Sadhu, sadhu, sadhu.
Recordings of Sayadaw U Silananda (Abdhidhamma, “Words of the Buddha”, …, dhamma talks given at the meditation retreats) were made by his disciples at Dhammacakka Center, Theravada Buddhist Society of America (TBSA), Tathagatha Meditation Center (TMC), Zen Buddhist Temple, … Some works are available as Audio CDs, MP3s, … and books.
I was fortunate to edit the dhamma talks (transcribed by Sayadaw U Osadha) before presenting them to Sayadawgyi U Silananda for final review and editing. The book was published in 2003 by the Malaysian yogis (led by Pauline Chiong).
Triple Gem Publications
Triple Gems Publications, in collaboration with Suki Hoti Publications, have made available dhamma dana books. See the relevant postings.
Selected Theravada Web Sites
Thanks to Dhamma Download Center (Ko Kyaw Lwin and team), Nibbana.com (Dr. Maung Maung Lwin and team), and several other Theravada web sites, the Teachings of the Buddha and His disciples can easily be studied, practiced, and propagated. Sadhu, sadhu, sadhu.
