Page 8: Trip Top Description
It also has two power supply settings - Cathode and Fixed bias to provide further tone structure. The Trip Top is designed to output approximately 30 watts in cathode bias mode and 40 watts in fixed bias mode using 6L6GC tubes. -

Quite simply, if players prefer the sound of tubes, they will continue to buy and use them. Below are some fundamentals. TrinityAmps Trip Top Builders Guide Ver1.9.docx Page - 14 -... -
Page 10: General Amplifier Operation
Overdrive the stuffing out of it. Tubes are very forgiving of massive overdrives, unlike solid state gear. As long as they tubes don't overheat for long periods, it's not fatal. TrinityAmps Trip Top Builders Guide Ver1.9.docx Page - 17 -... -

(i.e. .001uF) and it rolls off highs in the stage. Sometimes you see a high frequency roll off cap going from the plate pin to the cathode pin - 350pf->500pf in value. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 18 -... -
Page 12: Biasing Tube Amps
Aside from frying the tube this situation can potentially damage the output transformer, so if you ever see this happening while playing it's best to shut the amp down right away and have it serviced. This is an extreme situation that shouldn't happen under proper operating conditions. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 21 -... -

(2) Collect the ground points of each tube and its associated resistors and capacitors to a local ground point that is not connected to the chassis. Run one wire to the star ground point from each collection. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 22 -... -
Page 14: Tube Pin Numbering
6SL7 6L6 /KT88 The pins on the potentiometers are numbered 1 to 3 from left to right when the shaft is facing towards you and the pins are at the top. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 25 -... -

Page 17: Wiring
• Use Black, White 18 Gauge, stranded, for power supply hook up - to transformers from IEC socket. • Re-use cut offs from the transformers for the power supply side. • Use RG174U for coaxial connections as indicated on the layout TrinityAmps Trip Top Builders Guide Ver1.9.docx - 30 -... -
Page 18: Grounding Scheme
Grounding Scheme The TRIP TOP use a single star-point grounding scheme where the power side of the amp is connected to a single common ground point, and the preamp part is connected to the same point on the chassis. For grounding these amps, we strongly recommend that you follow the layout provided. -
Page 19: Install Transformers
Primary and Secondary leads going through separate grommets. Bolt the transformer in place with the supplied 4 each of 8-32 bolts & KEPS nuts. The secondary leads should be in-line with the impedance switch. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 32 -... -
Page 20: Power Supply Wiring
Route the twisted pair wire around the outside perimeter of the chassis, following the layout diagram, pressing it flat against the chassis. Cut, strip and solder them to the Rectifier tube, V6, pins 4 and 6. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 33 -... -
Page 21: Turret Board Construction
5 Turret Board Construction If you do not have a pre-built Trinity Amps turret board, now is the time to build it. Install the jumper wires indicated in Red on the underside or topside of the board. Which side you use is a personal preference. -
Page 22: Connecting The Turret Board
Connect 1K grid stopper resistors between pins 1 and 5 of V4 and V5. 6 Connecting the Turret Board Now is the time to make the connections from the turret board to the tubes. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 47 -... -

Connect the Red lead to the B+ turret at the 1K 10W resistor where the standby lead is connected to the board. Trinity Amps TRIP TOP Ampeg Design Output Transformer Connect the Impedance Selector and Speaker Output Jacks TrinityAmps Trip Top Builders Guide Ver1.9.docx... - Page 24 You should get a value 10 to 20% higher than the rated output voltage of 700 VAC. Measure all the other AC voltages (Heater to Rectifier and Tubes V1-V6 to ensure they are within spec of the provided transformer schematics and specs. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 55 -...
- Page 25 This should vary from approximately -40 VDC to -60 VDC as the Bias Adjustment Pot is turned. If it doesn’t, re-check your wiring. This is critical for the fixed bias mode to work properly. If this is confirmed, power down, remove Rectifier tube knowing the Trip Top DC supply is within spec. 9 Input Jacks Remove and assemble the input jacks as per layout with the 3.3M resistors and jumpers in place.
- Page 26 Set the control in mid position as starting point. Once the amp is operating correctly, rotate the control to minimize any hum and use your ears to tweak for lowest hum levels coming from the Trip Top. There should be very little hum.
- Page 27 The voltage should be very close to 40% higher than the raw AC. Assuming you measured, say, 700VAC across the full secondary in the above steps, then each half is delivering 360VAC. B+ will be ~40% above this, which is ~500VDC. TrinityAmps Trip Top Builders Guide Ver1.9.docx - 59 -...
- Page 28 Once the amp is operating correctly, turn the Hum Control Pot and use your ears to tune for lowest hum levels coming from the Amp. Hopefully, there are no problems but if you think there are e.g. hum, squeal etc., then move on to the troubleshooting section of this manual.

- Page 29 If your guitar's Volume pot is at zero, you'll find continuity to ground instead. You should get continuity between the tip and chassis with nothing plugged in because of the shorting jack and the cross over wire.
