00:09Hear top 5 deals right now.
00:12First, gold-plated 7-pin B7 G-socket.
00:16Costs $2.86.
00:19Gold pins prevent oxidation, keep signal quiet for 6x4 and 6z4 rectifier tubes.
00:25Tight pin grip stops contact hum.
00:28Cheap, reliable base for tube power stage.
00:32Second, 2-pack ceramic B7 G-chassis mount sockets.
00:36Costs $1.38 pair.
00:39Heavy ceramic takes extreme heat from 6z4 rectifier without melt risk.
00:45Solid chassis tabs mount cleanly.
00:48Best value for high-heat vintage builds.
00:51Third, 5-pack 2-247 high-power MOSFET transistors.
00:55Costs $9.07.
00:59Massive voltage headroom handles raw B-plus ripple filtering without breakdown.
01:04Replaces heavy chokes with clean solid-state regulation.
01:08Tough silicon, zero hum.
01:11Fourth, tube pre-amplifier PCB with onboard 6z4 and 6x4 tube rectifier layout.
01:17Costs $18.96.
01:20Thick copper traces route AC filament lines away from audiopath, kill buzz.
01:25Dedicated tube rectification gives smooth, natural DC rail.
01:30Fast route to clean pre-amp power.
01:33Fifth, 25-amp AC-DC rectifier filter power supply bare PCB.
01:38Costs $4.84.
01:41Thick traces take massive filter caps for stiff DC filament rails.
01:46Handles high continuous current without board scorch.
01:49Solid foundation for custom diode setups.
