I have a want for a static inverter-- 115V @ 400Hz. .Not a major load requirement as around 100 VA would suffice. Units that come to mind are PP - 6376/A, or PP - 6508/U or PP - 6674. Some of these have been used on OH-68A and AH-1G and OH-6A helicopters. Thanks for any assistance Pete D..Williams METUNG, 3904 AUSTRALIA jupete at bigpond.net.au
