broken transistor on av modded famicom

I have an av modded famicom (using this tutorial http://jpx72.detailne.sk/modd_files/fc/avmod.htm ) for quite some time. Unfortunately something moved inside and the transistor snapped.
The guide says that I can use any pnp transistor. My local electronics/hobby store suggsted a 2n3704 transistor.
Can I use that?

ps. I found an alternate guide which I was thinking to follow.
Will it be affected though from the lack of the original transistor that was originally? (this guide too suggests a 2n3704 transistor)

 

the original transistor is a 2SA937

 

I am not a electronics expert but they both are general purpose transistors and from what i could make out from the specs of the japanese datasheet of the original they are both pretty similair.

 

Use a 2N3906 instead and this schematic. It is the circuit the AV Famicom uses. Also, you can get a much better picture with the NESRGB board or the Hi Def NES HDMI kit. The NESRGB outputs composite video, S-Video, and RGBS via SCART. It also supports a RGB to YPbPr add-on.

 

What's the difference from this schematic to the one I've already used? Gives a better image?

The NESRGB kit is something I've been thinking to purchase, but I'm not confident yet in disoldering ic chips

 

It should give a better image from what I've seen but I could be wrong. You will still have jailbars but the fix I've seen requires desoldering the PPU and wrapping it in copper.

 

there should be enough room under the PPU to slide some copper tape under

 

Just replaced the original transistor with this one. Everything is back to normal
