DIY: Pass F5 turbo v2 initiated

[anilva]

Capt,

To be little more specific, the 100W light build is connected in series with the mains power supply and used to power on the amp for the first time. This will show if there is any short or improper current draw by the amp, when it is not yet been biased properly. If there is a fault the light bulb remains lighted. If there is no fault, the light bulb lights up and dims down to zero. Momentary light up is due to current draw for charging the large electrolytic cap bank.

This is the best way to test power circuits if you don't have a variac.

Cheers.

Buzzforb updated today - we are getting remaining batch of diodes within next 10 days. He got hold of all components and they are starting from USA by this week end. Thanks for patience.

So I will be running after cab fabricator and start me build soon after GR Reasearch speaker build.

Re: 15000 UF caps arived

I have received 15000 Uf CDE caps today.I request members to transfer their share to my bank account.I already paid interest on credit card.

I will start shipping kits in two days.

Will it be possible to publish a list of Components, So that we can cross check once we receive the components/kit.

Regards,

Vipin.

Layout suggestions required

Pardon me for some noob questions here after. Here are the first set of them.

plan to keep the toroids one over the other on the front side of the panel so that I can work freely towards the backside of the cabinet.

The pcbs can be placed parallel to the depth or perpendicular to the depth. Suggest me teh best possible way .

I guess I will leave atleast 1 inch from the back side from the back panel where I will have the cl60 placed.

Thanks
Pandu

My preference is for the 3rd picture as each board will feed it's amp pcb on that side and the wires do not need to run across.

I have received the CDE 15000 uF caps from Sachin and duly populated my boards and installed them in the F5 Turbo V2 build. They work perfectly and there is no more residual hum. I think the Ripple current and ESR qualities of these caps is very good and genuine.

I am in the process of putting together the Pass F5 V3 build which will require double the PS capability in terms of filter capacitance and current. I am requesting Sachin for additional 32 nos. of 15000 uF, 50V caps. I believe the minimum order quantity of these caps is 100. Anyone else is interested to add to the quantity of the caps to reach the magic 100 figure mark?

Thanks.

What if moves that rectifier board from middle of Filter to parallel between Transformer and filter boards?
This way both filter boards could be near to each other and capacitors are away from heatsink. I mean transformer and rectifier boards like first picture and filter boards like third picture but adjacent.

Good idea.

Thanks Anil,
I already got cap requests from Kroyin and Omishra.Total no of caps required by Fms
Anilva: 32
Omishra:16
Kroyin:8
Total = 56

Anilva & om

Thanks guys for your help.

Will start making holes into the base plate.

Thanks

Sachin,

When are you planning to mail my set of caps which you already received.

Thanks

Hi Pandu,
I am waiting NTCs and Trimmers from Om which he will send me after receiving Diodes from US.I can ship your remaining parts(caps and .22ohms resisters) tomorrow. Omishra will ship you NTCs separately.It will ad up in courier cost.

Regards,
Sachin

sachin,

received the Components by courier yesterday.

First of all the Quality of components and PCB was a treat for eyes and packing was awsome nothing less than professional. :clapping:

I will have to gather enough courage to touch the Iron with such a quality PCB.


So what is pending now, to receive from You/Omishra.

Thanks !!

Hi Vipin,
Thanks for your kind words.I will prepare a checklist tonight in excel and send to everyone.There are too many parts and I am not getting time.
Note: There are two types of Jfets K170 and J74(total 2 pairs) please solder according to their locations.Please don't solder 10 Omhs(Black) thermisters,Omishra will post the details regarding this.You will receive trimmers and NTCs from OM.

Regards,
Sachin

om & sachin,

If I can get the remaining parts by next week, I want get going on the christmas week.

Hi Pandu,
I will ship your remaining parts on Monday.Please PM me your mail id I will send you a checklist.Please crosscheck and varify what components are missing.I will pack everything on Sunday.

Pandu, I have everything except those diodes which are flown from Miami FL. now I have ready packed everything. I will make smaller parcels and send it after diodes arrival. Expecting those diodes by next weekend. In case of time crunch i can arrange personal pickup for you. Don't worry. Or I have to send two separate parcels.

Om,

I have the diodes from the first batch. I would need caps, bridge rectifier blocks and may be some of the pins( not sure). WIll check in the afternoon and let you know.

Edit:
This is what i got earlier shipment:

1UF & 10 UF 4 each capacitors
2.2K resistor 4
2.21k resistor 4
47.4k resistor 2
4.7K NTC 4
main switch contact 2 caps
1R 3w resistors 16
5k trimpots 4
220R 3w 8
200 trimpot 2
32 Yellow covered caps( I guess)
4 jfets
1k 6
10R 4
47.5R resistors 8
mosfets 8
diodes 24


pins
10 pcb tabs
62 pcb pins
clips

sleeves

Got it! You are missing one PCB clip type. Can you see what type/count you have, also cover bag named small/big? For you I have 2 bridge blocks and one power NTC pending. I will send it on Monday, Sachin forgot clips but he will add and adjust in next parcel for 16 x power caps, 16 x .22 ohm resistors and 2x black NTCs.

Please pm me your contact details/address.

Diodes are still in PO, BTW local parts are from

For each set -
Rs 385 all locally procured parts
Rs 225 all PCB pins and rubber sleeves for wire terminals
---------------------------
Rs 610 Sub Total-1

Tomorrow I will add Semiconductor import price (Approx Rs ~5000 for 24 diode+ matched Quad MOSFETs w/ previous ref of customs duty). I will start courier them from day after tomorrow. Anybody need details please drop me PM. In next couple of days I would be starting my build too.
