However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

The Radial J33 has been designed specifically for dynamic cartridges. Low noise RCA inputs have been fitted with the inclusion of an essential turntable ground lug. Equipped with a precision RIAA low pass filter, the J33 is tailored to produce a smooth, warm audio response. The signal is then buffered to provide the audio system with a standard -10dB signal with choice of RCA connectors for compatibility with home HiFi entertainment systems, 3.5mm (1/8") output to feed a laptop or iPod, or a stereo TRS 1/4" jack for an audio recorder. A second set of DI XLR outputs deliver a mic level signal to feed multicore, mic splitter and mixing desk preamp inputs. A low pass filter is also fitted for high sound pressure environments to reduce bothersome resonant feedback.

The J33 features a 14 gauge steel enclosure- a unique book-end design creates a protective zone around the switches and input connectors. An internal I-Beam construction ensures maximum rigidity, ensuring minimal stress on the sensitive internal solder joints.

The Radial J33 is a high performance turntable preamp ideally suited for music playback, archiving, DJing and sampling.
