Bernie German's full range was designed T-xx, from the minnow (a T-1) up to the mighty T-50 units, of which one;y ten were made I believe. I ordered the Laser transmitter be two T-25s, combined by a simple T network in the centre cabinet. This meant there was always one as backup for when one unit failed, as transmitters often do.

At sea it can be hell to try and get spares - it happened in Laser's early days when the modulation reactor was way over-driven, over-heated and melted many windings. It was fine into the dummy load, which was perfect Rr and Zero-J, but into the antenna the reactance ws awful and constantly changing. `solid state would never have tolerated it, but the tubes pumped away until the reactor gave up.

A replacement was flown over to Gatwick, but instead of being collected, it was addressed to "the Punch Tavern, Whitstable" and the crate showed up on a small flat-bed truck.
